38、ational Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees establish

39、ed by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the fie

40、ld of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC1. 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 least75% of the

41、national bodies casting a vote. International Standard ISO/IEC10089 was prepared by Joint Technical Committee ISO/IEC JTC1, Information technology.

This Intern

43、ational 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 definitions of the essential concepts; the environment in which the characteristics are to be tested; the environm

44、ents 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 the recording characteristics for recording the information, for reading the information and for erasing it

45、 many times, so as to provide physical interchangeability between data processing systems; two formats for the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used for recording and the quality of the recorded signals. 2 Conformance A 130mm rewritab

46、le optical disk cartridge is in conformance with this International Standard if it meets all the mandatory requirements of clauses8 to16, and either those of clause17 or those of clause18. 3 Normative references The following standards contain provisions which, through reference in this text, consti

47、tute provisions of this International Standard. At the time of publication, the editions indicated were 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 t

48、he standards listed below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 683-13:1986, Heat treatable steels, alloy steels and free-cutting steels Wrought stainless steels. IEC 950:1986, Safety of information technology equipment including electrical busine

49、ss equipment. 4 Conventions and notations The following conventions and notations apply in this International Standard. a) In each field the information is recorded so that the most significant byte (byte0) is recorded first. Within each byte the least significant bit is numbered bit0, the most significant bit (i.e. bit7 in an8-bit byte) is recorded first. This order of recording applies also to the data input of the error-correcting codes, to the cyclic redunda
