FCC INFORMATION  
The equipment described in this manual has been tested and found to comply with the limits for a Class  
B digital device in accordance with the specifications in Part 15 of FCC rules. These specifications are  
designed to provide reasonable protection against radio and television reception interference in a  
residential installation. There is no guarantee that interference will not occur in a particular installation.  
To determine if your CD-ROM drive is causing interference, turn the drive off. If the interference stops,  
it was most likely caused by the drive. To eliminate the interference, you may try one or more of the  
following corrective measures:  
·
·
·
verify the cables and connectors between components are shielded.  
increase separation between the drive and components.  
connect the drive into an outlet or circuit different from that which the components are  
connected.  
·
consult dealer or experienced radio/television technician for help.  
The Federal Communications Commission offers a handbook that may help you with eliminating  
interference. The handbook is titled Interference Handbook (stock number 004-000-00493-1) and may  
be ordered from the U.S. Government Printing Office, Washington, D.C. 20402.  
WARNING: Any changes or modifications to this product that are not authorized by Pioneer could void  
the FCC Certification and negate the user’s authority to operate the equipment.  
DOC CLASS B COMPLIANCE  
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus  
set out in the radio interference regulations of the Canadian Department of Communications.

PREFACE  
These specifications define the SCSI command set that defines the interface between a host computer and  
such primary devices as CD-ROM drives and CD-R writers.  
These are the control functions for the Pioneer DRM/DR-U series CD-ROM drives. For specific models,  
refer to Section 1.1 below.  
For details of the common standard of SCSI, refer to ANSI SCSI-2 working draft X3T9.2 revision 10K.  
For details regarding the use of the compact disc as a SCSI CD-ROM device, refer to the proposal made  
after the ANSI SCSI-2 working draft X3T9.2 revision 10K.  
For Compact Disc, CD-ROM disc, and CD-R disc specifications, refer to the Red Book, Yellow Book and  
Orange Book Part2.  
For file system specifications, refer to ISO 9660.  
For details about the use of SCSI Bus, refer to the installation manuals of the particular drives.  
For more information on player control commands (mnemonic commands), refer to Appendix B of this  
document and/or Pioneer Industrial LaserDisc Player (any model) User’s Manuals.  
THESE SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.  
1.1  
DRM/DR-U Series  
The six-disc DRM series drives are SCSI-21 CD-ROM minichangers using a single movable  
optical assembly and a removable Pioneer-developed 6-disc CD magazine. Six discs may be  
stored in individual trays in the magazine. Each tray swings out of the magazine into the drive  
assembly. Only one disc may be read at a time. The minichanger appears on the SCSI bus as one  
SCSI ID with six (6) logical units (0-5), one logical unit assigned per disc. The assignment of  
logical units to discs may be changed at any time.  
1
DRM-604X is the only minichanger that supports both the SCSI-1 and SCSI-2 command sets. Please refer to Pioneer’s DRM-600  
Series SCSI Command Reference Manual for details on the SCSI-1 command set.

The DRM-1804X is an 18-disc single drive SCSI-2 CD-ROM changer. It appears on the SCSI  
bus as one SCSI ID with two (2) logical units. The single CD-ROM reader is logical unit 0 and  
the changer is logical unit 1. For detail information, refer to Pioneer’s DRM-1804X CD-ROM  
Jukebox Changer Mechanism Controller SCSI Specifications, document number OB-U0084-B.  
The DRM series includes two jukebox changers - the DRM-1004X 100-disc CD-ROM changer  
and the DRM-5004X 500-disc CD-ROM changer. For detail information, refer to Pioneer  
publications DRM-1004X Series 100-Disc CD-ROM Changer Mechanism Controller  
Specifications, document number DSE-S035C and DRM-5004X Series 500-Disc CD-ROM  
Changer Mechanism Controller SCSI Specifications, document number OB-U0091-B,  
respectively.  
The DR-U series are SCSI-2 single disc CD-ROM drives. They appear on the SCSI bus as one  
SCSI ID with logical unit 0.  
The DR-D504X is a SCSI-2 single drive unit that is mounted into the DRM-5004X 500-disc  
jukebox changer. It is assigned one SCSI ID and logical unit 0. Refer to Pioneer’s DRM-5004X  
Series 500-Disc CD-ROM Changer Mechanism Controller SCSI Specifications, document  
number OB-U0091-B, for further details.  
Implementing Pioneer’s LaserDisc player technology, vendor unique SCSI commands support  
the alphanumeric player command set allowing CD audio control through use of simple  
mnemonic commands. Refer to Appendices A and B for further information.  
Table 1.1 on the opposite page lists the models supporting the SCSI-2 command set.  
1.2  
Drives Supported by this Manual  
Refer to Table 1-2 on the opposite page for drive versions that are supported by this manual. To  
determine what version your drive is, issue an IQUIRY command, reference Section 2.4. The  
drive’s response to the command will be to return the following information about the drive:  
Model Number;  
Vendor;  
Product Data; and  
Revision Number.

1.3  
SCSI Protocol  
The SCSI Protocol outlined in this section applies only to SCSI bus models. It does not support  
ATA bus models.  
1.3.1  
Command Link/Control Field  
The Control Field inside the Command Block is defined as:  
Bit  
7
6
5
4
3
2
1
0
Vendor Unique  
Reserved  
Flag  
Link  
The Command Link function is not supported by the DRM/DR-U Series. Set Flag and  
Link bits to “0” (FALSE).  
Set the RelAdr (Relative Address) bit, bit 0 of byte 1, inside the Command Block to  
“0” (FALSE).  
1.3.2  
Disconnect/Reselect  
Selection time-out period is 250 ms.  
If the initiator does not respond to reselection within the time-out period, the drive will  
release the bus for a minimum of 200 ms. The drive will then repeat the  
arbitration/reselection sequence until the initiator responds, issues BUS DEVICE  
RESET, or until the SCSI bus is reset. During a reselection retry, the drive will return  
BUSY to selection requests from any initiator.  
During execution of audio commands, if the disconnect/reselect function is selected,  
the drive disconnects from the initiator before execution a SEEK or other operation  
that requires head movement. When the selected address is located, the drive reselects  
the initiator and begins audio playback. The time needed for the reselection procedure  
is dependent upon the status of the SCSI bus. Audio playback may begin before the  
reselection is complete. Refer to Appendix A for more information.

Prefa c e  
1.3.3  
Status Phase  
Four status conditions are supported. They are  
GOOD  
00h  
02h  
08h  
18h  
CHECK CONDITION  
BUSY  
RESERVATION CONFLICT  
When the IMMED bit is set to “1” (TRUE) in a command block, the drive returns  
GOOD when the command is first interpreted. As the command is being executed, the  
drive returns BUSY to successive commands until operation of the first command is  
complete and the drive is ready to receive a new command.  
Refer to Section 2.31 REQUEST SENSE for details on deferred error reporting.  
1.3.4  
In-Phase/Out-Phase Messages  
The DRM/DR-U Series supports only those In-Phase and Out-Phase Messages that are  
listed below and on the following page. The drive will return a MESSAGE REJECT  
for any messages received other than those listed.  
Message Msg 05h + 09h will cause the drive to go to BUS FREE PHASE without a  
retry.

Address Format for Answering Occasion (MSF bit)  
With some commands, it is possible to choose either Logical Block Address or MSF Format  
with Address Field of answering data.  
MSF bit  
if “0” (FALSE), use Logical Block Address as CD-ROM Absolute Address or Track  
Relative Address. If Track Relative Address, the MSF bit is indicated by 2s sequences.  
if “1” (TRUE), MSF Format is used. Within the shift area, number declines by a positive  
number.  
1.5  
Sample Command  
The table on the opposite page outlines the command structure. Some commands apply to the  
entire drive. For these commands only, the LUN will be ignored.  
Commands with Logical Blocks, e.g. READ, VERIFY, have Allocation Length in Blocks. All  
others have Allocation Length in bytes. Some commands use Transfer Length instead of  
Allocation Length to specify the number of bytes that the initiator will transfer to the drive.  
3 For equipment supporting Change Definition Command, the DRM/DR-U Series drives have a Hardware Reset Option. In this case, the  
Change Definition chosen by the SCSI action definition would not be changed or initialized by either the SCSI BUS RESET or BUS  
DEVICE RESET message.

Audio Scan (1) (CDh)  
When AUDIO SCAN (1) is executed, the drive begins a high-speed scan from the Scan Start  
Address. The drive plays a block as it crosses each track. Each scan is approximately 15 seconds.  
When the specified search address is found, GOOD status is returned.  
If the drive is not ready or if the Scan Start Address is not on an audio track, Check Condition  
status is returned.  
During an audio scan, the drive can receive and execute the following SCSI commands without  
scan termination:  
AUDIO PLAY (StpAdr=1), AUDIO STATUS, AUDIO STOP  
INQUIRY  
MODE SELECT, MODE SENSE  
READ BUFFER, WRITE BUFFER  
READ CD-ROM CAPACITY, READ SUB CHANNEL, READ TOC  
RECEIVE DIAGNOSTIC RESULTS, REQUEST SENSE, TEST UNIT READY

There are several commands that when received by the drive during an audio scan, the drive will  
terminate the scan and execute the received command. The commands are:  
PLAY AUDIO (StpAdr=0), AUDIO SCAN, PLAY AUDIO TRACK  
PAUSE/RESUME  
READ, SEEK, VERIFY

Change Definition (40h)  
When executed, the CHANGE DEFINITION command modifies the operating definition of the  
drive regardless of the specified logical unit number.  
A SCSI reset or BUS DEVICE RESET will not affect the definition changed by the CHANGE  
DEFINITION command.  
Cycling the power to the drive OFF and ON will cause the operating definition to revert to the  
default setting.  
If the CHANGE DEFINITION command did not execute successfully, the operating definition  
will remain in the same status it was prior to the attempted execution of the CHANGE  
DEFINITION command.  
Operation Code is (40h).  
Save Control Bit (SCB)  
Must be set to “0” (FALSE).  
The drive will not save the operating definition. A power reset will set the drive to its initial  
operating definition.  
Definition Parameter specifies the operating definition. The Definition Parameter field supports  
the following field values:

2.5  
Mode Select(6) (15h)  
The MODE SELECT(6) command provides a range for the initiator specifying specific operating  
parameters, e.g., medium, logical unit and peripheral device parameters.  
IMPORTANT: Initiators should issue the MODE SENSE command (reference Section 2.7)  
prior to each execution of the MODE SELECT command to determine supported pages, page  
lengths and other parameters.  
Operating Code is (15h).  
PF (Page Format)  
Must be set to “1” (TRUE). The drive does not check the value of the Page Format bit.  
SP (Save Parameters)  
Must be set to “0” (FALSE). Parameter saving is not supported.  
Parameter List Length  
If “0” (ZERO), no data will be transferred.  
The Parameter List Length is the number of bytes of the Mode Select Parameter List that is  
to be transferred in the Data Out phase. A parameter list length that results in the truncation  
of any descriptor, header or page parameters will cause the target to terminate the  
command. In this case Check Condition Status (Sense Key : Illegal Request) is returned  
and Sense Code is set to Parameter List Length Error.  
Using the MODE SELECT command, the initiator can assign or alter parameters for the logical  
units. The Parameter List includes a 4-byte header, followed by 0-1 block descriptors and 0-N,  
where N is a whole number, page descriptions. Refer to Table 2-5A on the opposite page. The  
drive keeps parameters, the block descriptor and parts of page descriptors for each logical unit in  
its controller memory. When the drive is reset, the default parameter values are restored.  
Refer to Table 2-5B on the next page for details on the Block Descriptor format.  
Refer to Table 2-5C on the next page for details on the Page Descriptor format.  
After the MODE SELECT command is received, the drive returns Check Condition Status  
(Sense Key : Unit Attention) and sets sense key to Mode Select Parameter Changed for the first  
command received (except for INQUIRY or REQUEST SENSE) from any other initiator. The  
Sense Key Unit Attention is returned even if the parameters have not actually changed with the  
MODE SELECT command.

PAGE DESCRIPTOR  
Page Code indicates the meaning of the data contained in the page.  
Page Length is the number of bytes supported for each page. It does not include the page length  
byte.  
The drive will return Check Condition if ECC is enabled and the initiator accesses a Mode 1 or  
Mode 2 form1 data block and has specified 2336-, 2340-, or 2352 byte length.  
When the initiator accesses a Mode 2 form2 data block and has specified 2336-, 2340- or 2352-  
byte lengths, the ECC must be disabled. The drive will return Check Condition.  
The first two bytes of the page descriptor comprise the header which consists of the Page Code  
and Page Length. Following the header are the page definitions.

Error Recovery Parameters  
NOTE: When the bit definition of this error recovery parameter and the error recovery  
procedure (described later) are not in agreement, the error recovery procedure takes  
priority.  
DCR (Disable Correction)  
If “1”, data is transferred without Layered ECC (L-ECC) error correction.  
If “0”, L-ECC error correction is performed. The default value is 0.  
DTE (Disable Transfer on Error)  
If “0”, transfer of recovered data is allowed. The default value is 0.  
When both the DTE and PER bit are 1, the target stops the data transfer  
immediately if the error is detected, and then returns Check Condition status.  
NOTE: The TB bit controls whether data from the bad block is transferred.  
PER (Post Error)  
If 1”, the drive returns a Check Condition status for a recovered error.  
If “0”, no Check Condition status is returned for the recovered error.  
The default value is 0.  
EEC (Enable Early Correction)  
This bit must be 0: The defined retry procedure is performed prior to the error  
correction.  
RC (Read Continuous)  
Set to 0. A delay in the data transfer may occur due to an error recovery action.  
TB (Transfer Block)  
If “1”, uncorrected data blocks will be transferred to the initiator.  
If “0”, uncorrected data blocks are not transferred. The default value is 0.  
NOTE: in either case, the block address returned to the REQUEST SENSE command  
is not of the preceding good block but of the error block.  
Retry Number specifies how many times the drive re-tries a physical read operation  
when it finds an uncorrectable block. The default value is 4.

Description  
The maximum error recovery procedures available are used. If an error occurs which  
is uncorrectable with the error correction codes (ECC) on the media, data transfer is  
terminated with Check Condition status. The block with the error is not transferred.  
The sense key is set to Medium Error. The information bytes give the address of the  
block where the unrecovered error was detected. Recovered errors are not reported.

Only retries of the read operation and CIRC are used (layered error correction is not  
used). Only CIRC unrecovered data errors are reported. If a CIRC unrecovered data  
error occurs, data transfer is terminated with Check Condition status. The block with  
the error is not transferred. The sense key is set to Medium Error. The information  
bytes give the address of the block where the unrecovered error was detected.  
Recovered errors are not reported.

An error in a block had been detected by the EDC (Error Detection Code)  
but the error was recovered by read retry. Number of read retries to perform  
is specified with the Read Retry Number (the third byte of the Error  
Recovery Parameter page in the Mode Select command.). In this case, L-  
ECC (Layered Error Correction Code) is not used.  
2) Uncorrectable CIRC Error:  
L-ECC was not used, error could not be corrected by the CIRC after the

Disc numbers  
Shows the disk number assigned to each logical unit. Disc number 0 means that the  
associated logical unit cannot be used. Disc numbers in defaults are 1 through 6 for  
logical units 0 through 5, respectively.  
Accessing, with other SCSI commands, a logical unit to which disc number 0 has been  
assigned results in a Check Condition status with the sense data of "Illegal logical unit

Resume  
A Resume of zero indicates that the drive enter the hold track state with the audio output  
muted. A Resume bit of one indicates that the drive release the pause and begin play at the  
block following the last block played.  
The PAUSE/RESUME command requests that the drive start or stop the current audio play  
operation. This command is used with PLAY AUDIO commands, issued while the immediate  
bit(Immed) of MODE SELECT PAGE CODE E is set to one.  
This command is terminated with Check Condition status if the resume bit is zero and the audio  
play operation cannot be paused (i.e. an audio play operation has not been requested, or the  
requested audio play operation has been completed).  
It will not be considered an error to request a pause when a pause is already in effect or to request  
a resume when a play operation is in progress.

Operation Code is (45h).  
Logical Block Address  
The logical block address field specifies the logical block at which the audio play back  
operation will begin. If all bytes in the logical block address field are set to FFh, it means  
to start at the current optical head location. This feature allows the host to modify the audio  
ending address without interrupting the current audio playback operation.  
Transfer Length  
Specifies the number of contiguous logical blocks that will be played. A transfer length  
field of zero indicates that no audio operation will occur. This condition will not be  
considered an error. Any other value indicates the number of logical blocks that will be  
played.  
The PLAY AUDIO(10) command requests that the target play audio starting at the specified  
logical block address for the specified transfer length. The command function (Immed bit) and  
the output of audio signals will be as specified by the settings of the audio control parameters in  
the MODE SELECT PAGE CODE E.  
The status returning condition depends on the Immed bit of MODE SELECT page code E. The  
Immed bit in MODE SELECT page code E of one requests that this command return the status  
byte as soon as the audio playback operation has been started. The Immed bit in MODE  
SELECT page code E of zero requests that this command return the status byte when audio  
playback operation is completed, or an error occurs.  
If any commands related to audio operations are implemented then the PLAY AUDIO command  
will be implemented to allow a method for the initiator to determine if audio operations are  
supported. A target responding to a PLAY AUDIO command which has transfer length of zero  
with Check Condition status and setting the sense key to ILLEGAL REQUEST does not support  
audio play operations.

The Track Relative Logical Block Address field specifies the two's complement starting  
logical block address relative to the beginning of the first sector on the track with an index  
value of one. Negative values indicate a starting location within the audio pause area at the  
beginning of the requested track.  
Starting Track  
Specifies the track number of the starting audio track.  
Transfer Length  
The Transfer Length Field specifies the number of contiguous logical blocks that shall be  
output as audio data. A length of zero indicates that no audio playback operation shall  
occur. This condition is not an error. Any other value indicates the number of logical  
blocks that shall be output.  
The PLAY AUDIO TRACK RELATIVE(10) command requests that the drive begin an audio  
playback operation. The starting address is specified as a track relative logical block address  
within the specified starting track. The command function (Immed and SOTC bits) and the  
output of audio signals shall be as specified by the settings of the mode parameters.  
If the logical block length is not equal to the sector size the drive will adjust the starting logical  
block address and the transfer length. The drive will start the audio play operation with the  
beginning of a sector whenever the starting logical address falls within that sector (MSF unit). If  
the requested transfer length causes the end of an audio play operation to fall within a sector the  
drive will continue the play operation through the end of that sector.  
If the starting address is not found, or if the address is not within an audio track, or if a not ready  
condition exists, the command is terminated with Check Condition status.

Buffer Offset  
The byte offset in the buffer at which the read shall begin. This must be between 0 and 15.  
Allocation Length must include 4 byte header.  
This command is used with the WRITE BUFFER command to test the reliability of the drive  
command buffer memory and of the SCSI bus. This command does not cause a disc access. The  
drive terminates the DATA IN phase when it has transferred the header and data specified in  
Allocation Length, or the header and the remainder of the buffer.

If Allocation Length is 0, neither the header nor data are transferred.  
The header is defined as follows:  
- Effective Length  
The number of bytes of valid data in the buffer.  
The effective length does not depend on the actual number of data written by a WRITE BUFFER  
command. The sum of the buffer offset plus the effective data length is always 16. The number  
of data to be transferred following the header is the smaller one, either the allocated length minus  
4 bytes, or the effective length.  
When the drive cannot accept the specified buffer offset, a Check Condition is returned with the

The drive sends the initiator the 8-byte data as shown in Table 2-3 in the data transfer phase.  
Logical block address is the last logical block address on the disc.  
Logical block length is the size of logical blocks in bytes.  
The value of Logical Block Length returned depends on the block length set with a MODE

Support of Sub-channel data is optional. In the case of R-W the drive may return data de-  
interleaved and error-corrected, RAW or padded with zeros depending on the R-W Supported  
and R-W de-interleaved and error-corrected bits in the CD-ROM capabilities and mechanical  
status page.  
If the Starting Logical Block Address is set to FFFFFFFFh and the only information requested to  
be placed in the data stream is the Sub-channel data and there is currently a PLAY AUDIO  
command in process, the actual address used will be from the current location (of the Audio  
play).  
The number of bytes returned is based on which bits are set in the Data Selection Field.  
The table on the opposite page allows you to calculate the number of bytes returned based on  
which Data Selection field bits are set.  
The CD-DA audio data includes 16bits of information for each channel, and will be formatted as  
follows when an audio track is read. The First Channel is Left channel, and Right channel is  
next.

2.24 Read CDP (E4h)  
Operation Code is (E4h)  
This command requests the drive to return the status data resulting from the previous WRITE  
CDP command. The drive terminates the data phase when Allocation Length bytes or all the  
relevant data have been transferred.  
The last status data returned from the Drive Controller is buffered in the drive SCSI controller.  
Because the next return data from the next WRITE CDP command will overwrite the buffer, the  
READ CDP command should immediately follow a WRITE CDP command.  
The buffered status data is cleared after executing a READ CDP command. If a READ CDP  
command is issued after the buffer is cleared, the drive does not go to the data phase, but returns  
a GOOD status.  
If a READ CDP command is issued during the execution of a player operation, a BUSY status is  
returned. Any command other than the READ CDP is accepted. If the drive receives a SCSI  
command (except the INQUIRY or REQUEST SENSE commands) the action initiated by the  
WRITE CDP command will be terminated. In this case, the player status returned by the READ  
CDP command will be "E16" (Input From Other Device). Such a player interrupt does not cause  
any SCSI errors.  
See Appendix B for information on the CDP return codes.

MSF  
Set to 1 indicates that the absolute CD-ROM address field of the returned header data will  
indicate the MSF address where the specified logical block is found.  
If MSF bit is equal to 0, the absolute CD-ROM Address field of the returned header data  
gives the logical block address of the first logical block in the physical sector where the  
specified logical block is found. Note: This address may be different from the specified  
logical block address in CDB if the block length is either 512 or 1024 bytes.  
Logical Block Address  
Specifies the logical block at which the read header operation will begin. A logical block  
size smaller than 2048 bytes, will be mapped into the appropriate physical block from  
which the data would have been read.  
Allocation Length is the length of header data to be returned (08h).  
This command requests the drive to return the header data of the specified logical block to allow  
the system or applications to determine the mode of the specified block.  
If the specified block is on an audio track, a Check Condition status is returned.  
CD-ROM Data Mode  
The CD-ROM Data Mode field will return CD-ROM Data Mode of the specified logical

Audio Status indicates the status of an audio play operation. The status of audio commands are  
listed in Table 2-23C on the opposite page.  
Sub Channel Data Length should be set 0, 12, 20, 28 or 44 bytes and does not include the Sub  
Channel Header.  
ADR codes are defined in Table 2-23D  
Control bits are defined in Table 2-23E  
Track Number specifies the current Track Number  
Index Number specifies the current index number in the current track.  
Absolute CD-ROM Address returns the current location relative to the logical beginning of the  
media. If the MSF bit in the CDB is zero, this field is a logical block address. If the MSF bit in  
the CDB is one, this field is an Absolute MSF address.  
Track Relative CD-ROM Add returns the current location relative to the logical beginning of  
the current track. If the MSF bit is zero, this field is a track relative logical block address. If the  
current block is in the pre-gap area of a track, this address will be a negative value, expressed as a  
two's complement number. If the MSF bit is one, this field is an absolute MSF address.  
MCV  
If the MCV bit is one, the media catalog number field is valid.  
There are identify numbers according to the UPC/EAN cording in the media catalog  
number field. If all data in this field is ASCII 0, there is no media catalog number in the  
field.  
TCV  
If the TCV bit is one, the ISRC field is valid. In this field, there are identify numbers  
according to the ISRC standard. (DIN-31-621)  
When the Sub-Q bit in the CDB is set to zero, the drive returns the Sub Channel Header with no  
other data.  
Audio status values 13h and 14h return information on previous audio operations; they are  
returned only once after the condition has occurred. If another audio play operation is not  
requested, the audio status returned for subsequent READ SUB-CHANNEL commands is 15h.

2.28 Read TOC (43h)  
Operation Code is (43h).  
The READ TOC command requests the target transfers data from the table of contents to the  
initiator.  
This command has been modified from the SCSI-2 READ TOC command with the addition of  
the Format field to support multi-session discs.  
Format field  
00b  
Definition  
Same as SCSI-2. The Start Track Field specifies the starting track number  
for which the data will be returned. For multi-session discs, this command  
will return the TOC data for all sessions.  
01b  
This format returns the first session number, last session number and the  
starting address of the last session. The Start Track field is reserved and  
should be set to zero.  
10b  
11b  
All Sub-Channel Q code information.(DRM-602X only)  
Reserved.  
The Start Track field specifies the starting track number for which the data shall be returned. If  
this value is zero, the table of contents data shall begin with the first track on the medium. The  
data is returned in contiguous ascending track number order.  
If the Start Track field is not valid for the currently installed medium, the command shall be  
terminated with Check Condition status. The sense key shall be set to ILLEGAL REQUEST and  
the additional sense code set to INVALID FIELD IN CDB.  
IMPLEMENTORS NOTE: The maximum TOC data length possible on currently available CD-  
ROM media is 804 bytes, or 100 TOC track descriptors.  
The TOC data block contains a four byte header followed by zero or more TOC track descriptors.  
The TOC data length specifies the length in bytes of the following TOC data that is available to  
be transferred during the DATA IN phase. The TOC data length value does not include the TOC  
data length field itself.  
The first track number field indicates the first track number in the table of contents. The last  
track number field indicates the last track number in the table of contents before the lead-out  
track number.

IMPLEMENTORS NOTE:  
The first track number is not required to be one. A disc may start at any valid track  
number. The track numbers between the first track number and the last track number are  
required to be in contiguous ascending order, except for the lead-out track.  
The ADR field gives the type of information encoded in the Q sub-channel of the block where  
this TOC entry was found. The control field indicates the attributes of the track.  
The track number field indicates the track number for which the data in the TOC track descriptor  
is valid. A track number of 0AAh indicates the track descriptor is for the start of the lead-out  
area.  
The absolute CD-ROM address contains the address of the first block with user information for  
that track number as read from the table of contents. An MSF bit of zero indicates that the  
absolute CD-ROM address field contains a logical block address. An MSF bit of one indicates  
the absolute CD-ROM address field contains an MSF address.  
IMPLEMENTORS NOTE:  
The starting logical block address value recovered from the TOC has a tolerance of zero for  
data tracks and plus or minus 75 CD sectors for audio tracks. This tolerance is multiplied  
by a factor dependent of the logical block length.

Operation Code is (03h).  
The REQUEST SENSE command requests the drive to transfer extended sense data to the  
initiator. The drive supports the first 18 bytes of the extended sense data format. The drive will  
transfer Allocation Length bytes or 18 bytes, whichever is smaller.  
Valid  
A valid bit of zero indicates that the information field is not as defined in the SCSI-2  
standard. A valid bit of one indicates the information field contains valid information as  
defined in the SCSI-2 specifications.  
FileMk (File mark) if one indicates that the current command has read a file mark.  
EOM (End of Medium) if one indicates that an end-of-medium condition exists.  
ILI (Incorrect Length Indicator)  
An incorrect length indicator bit set to one indicates that the requested logical block length  
did not match the logical block length of the data on the medium.  
Sense Key  
Provides generic categories in which error and exception conditions can be reported. Table  
2-31B lists the supported sense keys.  
ASC / ASCQ (Additional Sense Codes)/(Additional Sense Code Qualifier)  
Additional sense codes and additional sense code qualifier provides further detail  
describing the sense key. These codes are listed in Table 2-31C.  
Additional Sense Length  
Indicates the number of additional sense bytes to follow. If the allocation length of the  
command descriptor block is to small to transfer all of the additional sense bytes, the  
additional sense length is not adjusted to reflect the truncation.  
Command Specific Info  
The field contains information that depends on the command which was executed. Further  
definition for this field is contained within the command description.  
SKSV  
(Sense Key Specific Valid) The sense-key specific field is defined when the sense-key  
specific valid (SKSV) bit is one. A SKSV value of zero indicates that this field is not

The SCSI ID of another initiator for which the logical unit shall be reserved.  
Ext. (Extent) is not supported. This bit must be 0.  
Reservation ID is not supported. This byte must be 00h.  
Extent List length is not supported. These bytes must be 00h.  
The initiator uses this command to exclusively reserve the specified logical unit. Area  
reservations using the Extent bit are not supported. If the 3rd Party bit is 1, the logical unit is  
reserved for another SCSI device specified by the 3rd Party Device ID. The initiator can change  
the reservation by issuing a new RESERVE UNIT command to the reserved unit. In this case,  
the previous reservation is released when the new reservation is received.  
The reserved condition is maintained until the original initiator issues another valid RESERVE  
UNIT command or a RELEASE UNIT command; when a BUS DEVICE RESET message is  
issued by any initiator; or when a hardware reset condition occurs. In the latter two reset cases, a  
UNIT ATTENTION condition is reported for the next SCSI command.  
Any reservation request by an initiator for a logical unit that has been reserved by another  
initiator is rejected, and a RESERVATION CONFLICT status is returned.  
If the 3rd Party bit is 1, the logical unit is reserved for the SCSI device indicated by the 3rd-  
Party Device ID. The reserved state is maintained as described previously. Any release request  
is ignored, and a GOOD status is returned if it comes from an initiator other than the one that  
issued the reservation command.

Operation Code is (00h).  
The TEST UNIT READY command checks that a cartridge is loaded and that the drive is ready  
to operate. "Ready" has different meanings depending on whether the drive has accessed a  
logical unit by loading the disc tray:  
Before access to logical unit : Magazine is inserted and the drive is ready to read.  
After an access to logical unit: A disc is in the specified logical unit (or tray) and is ready to  
be accessed.  
The TEST UNIT READY command does not load the logical unit's tray. (See REZERO UNIT)  
See 1.3 for Disc Status Information.  
A Not Ready condition can occur when:  
(1) No magazine is inserted in the drive.  
(2) The magazine cannot be inserted or ejected.  
(3) The drive cannot read TOC information on a disc.  
(4) There is no disc present.

Write Buffer  
2.44 Write Buffer (3Bh)  
Operation Code is (3Bh).  
Mode specifies meaning of the Buffer Offset field.  
Buffer ID is not supported. This byte must be 00h.  
Buffer Offset is the byte offset in the buffer where the data shall be stored. This must be 0  
through 15.  
Transfer Length is the number of bytes to be transferred in the DATA OUT phase. This must  
be the data length to be sent plus 4 bytes (header size).  
This command is to be used with the READ BUFFER command to test the reliability of the  
command buffer memory in the drive, and of the SCSI bus. The drive does not access any discs.  
Mode

Header, data, and buffer offset are 0s.  
01b  
Buffer offset indicates the offset of the buffer at which data are to be stored.  
10b  
Reserved  
Reserved  
11b  
The transfer length must include the 4-byte header, therefore, the actual data length to be stored  
is the transfer length minus 4 bytes. As the buffer length of the drive is 16 bytes, the maximum  
number of bytes that can be specified for Buffer Offset is 15, and the maximum for Transfer  
Length is 20.  
If Transfer length is larger than 20, a Check Condition is returned with the sense key "ILLEGAL  
REQUEST." Check Condition will also be returned if the Buffer Offset + Transfer Length is  
larger than 20.  
If Buffer Offset is not 0 when Mode is 00h, Check Condition is returned.  
Refer to Table 2-38A on the opposite page for the 4-byte header of 00h's must be sent preceding  
the test data.

Operation Code is (E3h).  
Transfer Length is the number of bytes of CDP command data to be sent.  
This command sends alphanumeric Player Control commands to the drive. The drive returns the  
command status after the player control command is transferred to the drive controller chip. A  
GOOD status indicates only that the command was syntactically correct. The READ CDP  
command must be used to determine the results of the operation.  
(See Appendices A and B for details on audio functions.)  
The Player Control command data can contain up to 21 characters including a Carriage Return  
(0Dh). If Transfer Length is larger than 21, Check Condition is returned with sense key  
ILLEGAL REQUEST and sense code 24h, "Invalid Command Block Other Than 20 or 21".  
IMPORTANT: THE COMMAND STRING MUST BE TERMINATED WITH A CARRIAGE  
RETURN  
Data after a Carriage Return is ignored. When there is no Carriage Return, Check Condition is  
returned with sense key ILLEGAL REQUEST, sense code "Error in Parameter List" (26h).  
When media change is prohibited by the PREVENT/ALLOW MEDIA REMOVAL command,  
the magazine eject command "Z0" is ignored. When the command string consists of multiple  
request commands (such as "?Z"), only the status of the first command is returned by the READ  
CDP command.

C D-ROM SC SI-2 C OMMAND REFERENC E MANUAL VERSION 3.1 (OB-U0077C )  
NOTES:  
1) The CD-DA block lengths are totally irrelevant to the logical block length set by the  
Mode Select(6) command. This command would not change the block length field in the  
MODE SELECT command.  
2) While the SCSI buffer is being filled, the drive is able to prepare with no overlap or  
missing data in response to the consecutive commands which read contiguous CD-DA  
blocks.  
When the host cannot read the data quick enough and the buffer is full, the drive will stop  
refilling the buffer. The host is still capable of reading all CD-DA data in the SCSI buffer  
with consecutive read commands without overlap or missing bits at the block boundary.  
Once the buffer is full, the first read command to read the next sequential CD-DA  
block(e.g. X+1) after the last CD-DA block(e.g. X) in the buffer will cause a Check  
Condition with a sense key of 05h and an additional sense code of BAh(buffer overflow).  
There is no check condition for a read command which does not request block X+1(e.g. a  
Read(X+2, 1) command). In addition, a second read command which requests block X+1  
will not get a check condition.  
For Example (In case that the last CD-DA block stored in the buffer is X):  
In a Read(X-2, 5) command to read block X-2 to X+2, the drive returns three CD- DA data  
blocks and then a check condition. The drive returns the block X+1 address in the  
information bytes(byte 3 to 6) of a subsequent Request Sense command. There are no  
overlap of missing bits for blocks X-2, X-1 and X. Block X and X+1 are not transferred.  
That is; in case of reading CD-DA blocks, the drive has only rough access. Once the data  
stream from the media has been stopped, it is unable to have such pin-point access as in  
CD-ROM blocks. (Each CD-ROM block always includes the CD-ROM Header that  
provides the pin-point access.)  
3) The volume level control is not performed on any SCSI CD-DA data. Analog audio  
output is not performed while SCSI CD-DA data is in transaction, either.  
4) The drive transfers data to the host at the burst transfer rate for the entire block of data.  
The drive's firmware overhead should only occur at a block boundary. Upon completion of  
the read operation, the drive enters the Hold Track state during inactive time.

The READ CD-DA MSF command requests that the drive transfer CD-DA data.  
The data transfer length (bytes) is calculated as follows;  
Data Transfer Length = [(Me-Ms) * 60 * 75 + (Se-Ss) * 75 + (Fe-Fs)] * CD-DA Block length  
(Ms, Ss, Fs) = Starting MSF address  
(Me, Se, Fe) = Ending MSF address

Transfer Length indicates the number of contiguous sub-code frames to be transferred. Each  
sub-code frame consists of 96-byte data.  
Read All Subcode command directs the target to transfer real-time sub-code data (P-W) to the  
initiator while the audio is being played.  
The initiator must hold while the current sub-code is being retrieved from the disc.  
If the Transfer Length is zero, sub-code data will not be transferred. In this case, however, it is  
not considered an error.  
In the event the sub-code buffer is full in the drive, the drive will stop storing sub-code data into  
the buffer. However, the data in the buffer is accessible by this command.  
The drive will quit the operation with a Check Condition status once the buffer overflows  
or there is no more valid sub-code data in the buffer. The sense key is set to 05h and the  
additional sense code is to BFh. The Check Condition for buffer overflow occurs only for the  
READ ALL SUBCODE command.  
If the target is not playing the audio, the drive will return a Check Condition status.  
The sense key is set to 05h and the additional sense code is to 64h.  
NOTE: The drive transfers an entire block of data at SCSI bus burst transfer rate. The drive's  
firmware overhead only occurs at a block boundary. Upon completion of the read operation, the  
drive enters the Hold Track state during the inactivity time.

Appendix A  
APPENDIX A PIONEER CD-ROM DRIVES - AUDIO FUNCTIONS  
The CD-ROM drives consist of two logical subsystems - a CD reader and a controller. The controller  
receives SCSI commands, and sends commands to the reader for execution as needed. This allows audio  
commands to be executed in the background. At times, the two subsystems may be operating  
independently.  
In addition to the normal audio commands, the CD-ROM drives support the Pioneer Laser Disc Player  
control commands. These alphanumeric mnemonics may be sent to the drive using the vendor-unique  
command WRITE CDP (Character Device Player). The WRITE READ CDP command strings are  
passed through the controller directly to the reader. The controller checks the length and termination of  
the command string, and, if valid, returns a GOOD status. The controller will generate a Check  
Condition with a sense key of ILLEGAL REQUEST if the string is not valid. The controller then passes  
the command string to the reader for execution. To receive the results of the command string, the  
initiator must use the READ CDP command to get the status from the reader. The reader passes the  
result data through the controller. Invalid commands or execution errors will not cause SCSI errors, but  
will be reported by the READ CDP command.  
Certain types of data, such as the disc TOC, are stored by the controller once they have been read from  
the disc. If a disc has been accessed, a READ TOC command will not require a disc access, which could  
include a disc change. Instead, the TOC data is transferred from controller memory.
