This document is identical to ISO/IEC 13842: 1995 and the following four paragraphs are the original fore- word as it appeared in that document.) IS0 (the International
30、Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by th
31、e respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of in
32、formation technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopt- ed by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75% of the nati
33、onal bodies casting a vote. International Standard ISO/IEC 13842 was prepared by Joint Technical Committee ISO/IEC JTC 1, information technology, Subcommittee SC23, Optical disk cartridges for information interchange. Annexes A to N form an integral part of this International Standard. Annexes P to
34、V are for information only. Requests for interpretation, suggestions for improvement or addenda, or defect reports are welcome. They should be sent to the X3 Secretariat, Information Technology Industry Council, 1250 Eye Street, NW, Suite 200, Washington, DC 200053922. This standard was processed an
35、d approved for submittal to ANSI by Accredited Standards Committee on Information Technology, X3. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. At the time it approved this standard, the X3 Committee had the following members: James

Together with a Standard for volume and file structure it provides for full data interchange between data processing systems. 2 Conformance 2.1 Optical Disk Cartridge (ODC) An ODC claiming conformance with this International Standard shall specify the Type of its two sides. It
41、 shall be in conformance if it meets all mandatory requirements specified herein for those Types of sides. 2.2 Generating system A claim of conformance with this International Standard shall specify which of Types R/W, R/W-R, P-ROM, P-ROM-R, O- ROM, O-ROM-R, WO, WO-R, and B is(are) supported. A syst
42、em generating an ODC for interchange shall be entitled to claim conformance with this International Standard if it meets the mandatory requirements of this Standard for the Type(s) supported. 2.3 Receiving system A claim of conformance with this International Standard shall specify which Type(s) of
43、side(s) is(are) supported. A system receiving an ODC for interchange shall be entitled to claim conformance with this International Standard if it is able to handle any recording made on the cartridge according to 2.1 on the Types specified. 2.4 Compatibility statement A claim of conformance by a ge
44、nerating or receiving system with this International Standard shall include a statement listing any other International Optical Disk Cartridge Standard supported. This statement shall specify the number of the Standard (s), including, where appropriate, the ODC Type(s), or the Types of side, and whe
45、ther support includes reading only or both reading and writing. 1 ISOhEC 13842:1995 (E) ISO/IEC 3 Normative reference The following standard contains provisions which. through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indica
46、ted was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standard indicated below Members of IEC and IS0 maintain registers of currently valid Interna
47、tional Standards. IEC 950: 1991, Safety of information technology equipment, including electrical business equipment. 4 Definitions For the purpose of this International Standard, the following definitions apply. 4.1 band: An annular area within the user zone on the disk having a constant clock freq
48、uency. 4.2 case: The housing for an optical disk, that protects the disk and facilitates disk interchange. 4.3 clamping zone: The annular part of the disk within which the clamping force is applied by the clamping device. 4.4 control track: A track containing the information on media parameters and
49、format necessary for writing, reading and erasing the remaining tracks on the optical disk. 4.5 Cyclic Redundancy Check (CRC): A method for detecting errors in data. 4.6 defect management: A method for handling the defective areas on the disk. 4.7 disk reference plane: A plane defined by the perfectly flat annular surface of an ideal spindle onto which the clamping zone of the disk is clamped, and which is normal to the axis of rotation. 4.8 entrance surface: The surface of the disk on to which the optical beam first impinges. 4.9 Error Correction Code (ECC)
