The set of AT Attachment standards consists of this document and the ATA implementation standards described in AT Attachment - 8 ATA/ATAPI Architecture Model (ATA8-AAM).

This document provides a common command set for systems manufacturers, system integrators, software suppliers, and suppliers of storage devices that provide one or more of the zones feature sets. Figure 1 shows the relationship of This document to other ATA standards as well as related device and host standards and specifications (e.g., SCSI standards and SATA-I0 specifications).
