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.
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: Vendor Unique The Command Link function is not supported by the DRM/DR-U Series. Set Flag and Link bits to “0”...
1.3.3 Status Phase Four status conditions are supported. They are 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.
CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) 1-5 S ABLE AMPLE OMMAND Byte Logical Number Operation Code : Logical Unit Number specifies which Logical Unit the command applies to. Logical Block Address specifies which Logical Block Address (LBA) the operation is to start.
Message Out-Phase (issued by host computer) 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.

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.

2.9.1 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.
CD-ROM SCSI-2 COMMAND REFERENCE MANUAL VERSION 3.1 (OB-U0077C) 2-9-1B E ABLE Value 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.
2-9-1B E ABLE RROR ECOVERY Value Description If data transfer can be maintained, the maximum error recovery procedures available are used. (RC=1) If an error occurs which is uncorrectable with the error correction codes (ECC) on the media, or is uncorrectable in time to maintain data transfer, the data transfer is not terminated.
2-9-1B E ABLE RROR ECOVERY Value Description Only retries of the read operation and CIRC are used (layered error correction is not used). Only CIRC unrecovered data errors are reported. If an CIRC unrecovered data error occurs data transfer is terminated with Check Condition status. The block with the error is transferred.
Page 56
The CD-ROM errors are: 1) Recovered CIRC (Cross Interleaved Reed-Solomon Code) Error: 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.).

If the initiator requests a disconnect, the drive disconnects from it during load and seek operations.

Allocation length set to 0 when Self bit is one. When Self bit is 0, set to 8h. This command reports the results of the drive's power-on self test (when the self bit is one).
2.37 Set CD-ROM Speed(1) (DAh) Operation code is (DAh). The Set CD-ROM Speed command provides a means for initiator to set the spindle motor speed. Speed Field Value Other Value Drive Differences: DRM-602x The DRM-602x does not support 4x speed. A speed setting value of 03h will not cause an error, but set the drive to 2x speed.

2.39 Start/Stop Unit (1Bh) Operation code is (1Bh). Immed (Immediate) When the immediate bit is 1, status is returned before executing the command . When it is 0, status is returned after the operation is completed. LoEj (Load Eject) When LoEj is 1 and Start is 0, the drive ejects the magazine. Start When Start is 1, the disc tray is loaded, the disc is spun up, and the laser and servo system are turned on.
2.41 Test Unit Ready (00h) 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.
Verify(10) 2.42 Verify(10) (2Fh) Operation code is (2Fh). Logical Block Address is the address at which the verify operation shall begin. Verification Length is the number of logical blocks to be verified. This command requests the drive to check the specified blocks on the disc based upon the error recovery parameter setting (see MODE SELECT command).
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.

Write CDP 2.45 Write CDP (E3h) 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 CD-DA command requests that the drive transfer CD-DA data and/or Sub Code data. The Starting Logical Block Address specifies the block where the READ operation begins. The definition of the starting logical block address is as follows: Starting Logical Block Address = (M-Ms) * 60 * 75 + (S-Ss) * 75 + (F-Fs) (M, S, F) = absolute MSF address of the requested starting logical block...

Operation Code is (DFh) 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.
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.
