CDU-541 CD-ROM DRIVE SCSI INTERFACE MANUAL
1. Preface
This document details the implementation of a SCSI command set for a Read-
Only device type (i.e. CD-ROM). This implementation complies with the ANSI
X3.131-1986 standard. In addition several of the concepts proposed in the
common command set document for direct-access devices have been incorporated.
There are extensions to the SCSI interface included for audio control.
This implementation represents the best information available to Sony
Engineering at the time. There is continuing work in the X3T9.2 committee to
develop an SCSI-2 standard that will incorporate CD-ROM commands as well as
extensions to the original SCSI standard. It is Sony Engineering's intention
to comply with the proposed.SCSI-2 document at the earliest feasible date. At
this time it is expected that most of the current implementation will comply
with SCSI-2. However the commands used for audio control are still
controversial and most likely will change in a future firmware release.
\,
Information about the current status of the audio commands and the proposed
SCSI-2 interface for CD-ROM can be obtained from Sony CD-ROM Engineering.
2. Introduction
This document covers the Sony CDU-541 CD-ROM drives. The CDU-541 is a half-
height CD-ROM drive which embeds a drive, a SCSI controller and a
audio/headphone
circuit. Not only SCSI commands but also SCSI-2 commands
which relate to the audio function are supported in this model. All commands
supported are described in alphabetic order in this document.
3. Physical Characteristics
The Sony SCSI controller uses a single-ended asynchronous SCSI interface
that complies with the physical characteristics of ANSI X3.131-1986 Section
4.0. Please refer to that standard for detailed information.
