35、dardization. National bodies that are members of ISOorIEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO andIEC technical committees collaborate in fields of m
36、utual interest. Other International Organizations, governmental and non-governmental, in liaison with ISOandIEC, also take part in the work. In the field of information technology, ISOandIEC have established a joint technical committee, ISO/IECJTC1. Draft International Standards adopted by the joint
37、 technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least75% of the national bodies casting a vote. International Standard ISO/IEC11560 was prepared by the European Computer Manufacturers Association (as Standard ECMA-15
38、3) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC1, Information technology, in parallel with its approval by national bodies of ISOandIEC. Annex A, Annex B, Annex C, Annex F, Annex G and Annex L form an integral part of this International Standard.

42、the information to be written once only and read many times, using the magneto-optical effect. This International Standard together with a standard for volume and file structure provides for full data interchange between data processing systems. 1 Scope This International Standard specifies definiti
43、ons of the essential concepts; the environment in which the characteristics are to be tested; the environments in which the cartridge are to be operated and stored; the mechanical, physical and dimensional characteristics of the case and of the optical disk; the magneto-optical characteristics and t
44、he recording characteristics for initializing the disk once, for recording the information once, for reading it many times, so as to provide physical interchangeability between data processing systems; the format for the physical disposition of the tracks and sectors, the error correction codes, the
45、 modulation method used for recording and the quality of the recorded signals. 2 Conformance A130mm optical disk cartridge is in conformance with this International Standard if it meets all the mandatory requirements specified herein. 3 Normative references The following standards contain provisions
46、 which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibili
