2、ry CouncilApproved December 7, 2010American National Standards Institute, Inc.AbstractThis standard defines a SCSI-based command set needed to access multi-media features. The applicableclauses of this standard, when used in conjunction with other standards and publications, define a fullstandard se
3、t of commands.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of th e ANSI Boar d ofStandards Review, substantial
4、 agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of
