National bodies that are

30、 members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other internationa

31、l organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the

32、ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at leas

33、t 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 20162 was prepared by ECM

34、A (as ECMA-317) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. Annexes A to L form a normative part of this International Standard. Annexes M to Q are for in

35、formation only. INTERNATIONAL STANDARD ISO/IEC 20162:2001(E) ISO/IEC 2001 All rights reserved 1Information technology Data interchange on 300 mm optical disk cartridges of type WORM (Write Once Read Many) using irreversible effects Capacity: 30 Gbytes per cartridge Section 1 General 1 Scope This Int

36、ernational Standard specifies the characteristics of a 300 mm optical disk cartridge (ODC) of Type WORM (Write Once Read Many) using irreversible effects, with a capacity of 30 Gbytes. This WORM ODCs uses writing effects that are inherently irreversible. Written marks cannot be erased and attempted

37、modifications of the written marks are detectable. This International Standard specifies the conditions for conformance testing and the Reference Drive; the environments in which the cartridges are to be operated and stored; the mechanical, physical and dimensional characteristics of the cartridge,

38、so as to provide mechanical interchange ability between data processing systems; the format of the information on the disk, both pre-written and user-written, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used; the characteristics of

39、 the prerecorded information on the disk; the recording characteristics of the disk, enabling processing systems to write data onto the disk; the minimum quality of user-written data on the disk, enabling data processing systems to read data from the disk. This International Standard provides for in

40、terchange between optical disk drives. 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 Optical Disk Cartridge shall be in conformance with this International Standard if it

41、 meets the mandatory requirements specified herein. 2.2 Generating System A generating system shall be in conformance with this International Standard if the ODC it generates is in accordance with 2.1. 2.3 Receiving System A receiving system shall be in conformance with this International Standard i

42、f it is able to handle an ODC according to 2.1. 2.4 Compatibility statement A claim of conformance by a generating or receiving system with this International Standard shall include a statement listing any other ECMA or International Optical Disk Cartridge standard(s) supported by the system for whi

43、ch conformance is claimed. This statement shall specify the number of the standard(s), including, where appropriate, the ODC Type(s), or the Types of side, and whether support includes reading only or both reading and writing. 3 Normative references The following normative documents contain provisio

44、ns which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate t

45、he possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
