3、 Industry CouncilApproved June 14, 2011American National Standards Institute, Inc.AbstractThis standard specifies the device model and functional requirements for the SCSI sequential-accessdevice type. This standards permits the SCSI sequential-access device type to attach to computers andprovides t
4、he definitions for their use.This standard does not contain material related to any service delivery subsystem which is used totransport the commands, command parameter logical block, command response logical block, andstatus specified in this standard.Copyright American National Standards Institute

6、 developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that al
7、lviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchas
8、ing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue ani
9、nterpretation of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised or
10、withdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard.
