Overview
ISO/IEC 14776-362:2006 - Small Computer System Interface (SCSI) Part 362: Multimedia commands-2 (MMC-2) specifies the SCSI command set extensions used to access multimedia features on optical and other media devices. Known as MMC-2, this International Standard extends SCSI for CD/DVD device models, feature and profile definitions, mode pages, detailed command descriptions (read, write, format, control), error reporting and compliance requirements for interfaces such as ATAPI and SBP-2. It is essential for implementing and interoperating with optical drives and multimedia SCSI devices.
Key Topics
- C/DVD device models: logical block addressing, multi-session and track topology, CD and DVD-specific structures, ECC/sector configuration, removable medium behavior and changers.
- Features & profiles: feature codes and profile lists (CD-ROM, CD-R, DVD-ROM, DVD-R/W, etc.), persistent/current bits and profile parameters for drive capabilities.
- Mode pages & parameters: mode select/sense pages for read/write behavior, error recovery, write parameters, CD audio control, power and timeout settings.
- Command set (MMC-2): comprehensive SCSI multimedia commands such as BLANK, CLOSE TRACK/SESSION, GET CONFIGURATION, READ/WRITE (including READ CD, READ DVD STRUCTURE), REPORT/ SEND KEY, PLAY/PAUSE, LOAD/UNLOAD, SYNCHRONIZE CACHE and many others with command formats and expected responses.
- Error reporting & sense data: additional sense codes for CD, deferred error handling and failure reporting control.
- Copy protection & security: DVD-CSS and REPORT/SEND KEY mechanisms for content protection are addressed.
- Interoperability annexes: normative guidance for ATAPI compliance and SBP-2 (serial bus protocol) storage model implementation.
Applications
- Optical drive manufacturers and firmware engineers: implement MMC-2 commands, feature profiles and mode pages for compliant CD/DVD drives.
- Operating system and driver developers: integrate SCSI/MMC-2 command handling in kernel-level drivers, media stacks and device drivers.
- Burning and authoring software: use defined commands for writing, finalizing and manipulating sessions/tracks on optical media.
- Storage integrators and test labs: validate conformity, implement ATAPI/SBP-2 interoperability and perform compliance testing.
- Forensics and archival tools: reliably read complex CD/DVD structures and multi-session discs per standard behavior.
Related Standards

- MMC series (Multimedia Commands) - this document is MMC-2 and complements other MMC parts
- ATAPI and SBP-2 specifications - annexes in MMC-2 provide mapping and compliance requirements
