scope:
This part of ISO/IEC 14776 defines the command set extensions in order to facilitate operation of the sequential-access device type. This part of ISO/IEC 14776, implemented in conjunction with the requirements of the SCSI Architecture Model-4 (SAM-4) standard and the applicable clauses of the SCSI Primary Commands-4 (SPC-4) standard, fully specify the standard command set for the sequential-access device type.
This standard provides the following:
a) it permits an application client to communicate over a SCSI service delivery subsystem, with a logical unit that declares itself to be a sequential-access device in the PERIPHERAL DEVICE TYPE field of the standard INQUIRY data (see SPC-4);
b) it defines commands unique to the sequential-access device type; and
c) it defines commands in order to manage the operation of the sequential-access device type.
This standard makes obsolete the following concepts from previous versions of this standard:
a) the GAP SIZE field;
b) RSMK and setmarks; and
c) Attached Media Changer model.
The term SCSI is used to refer to the family of standards described in this clause.
