34、 102R - Recommendation for transportation 104ISO/IEC 15898:1998 (E) ISO/IECviiiForewordISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form thespecialized system for worldwide standardization. National bodies that are members of ISO or
35、 IEC participate in thedevelopment of International Standards through technical committees established by the respective organization to deal withparticular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Otherinternational organizations, gove
36、rnmental 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. DraftInternational Standards adopted by the joint technical committee are circulated to national bod
37、ies for voting. Publication as anInternational Standard requires approval by at least 75 % of the national bodies casting a vote.International Standard ISO/IEC 15898 was prepared by ECMA (as ECMA-260) and was adopted, under a special “fast-trackprocedure”, by Joint Technical Committee ISO/IEC JTC 1,

40、.This International Standard specifies: definitions of essential concepts, the environment in which the characteristics shall be tested, the environments in which the cartridge shall be operated and stored, the mechanical, physical and dimensional characteristics of the case and of the optical disk,
41、 the optical characteristics and the recording characteristics for recording the information once and for reading it manytimes, 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,
42、 the modulation methods usedfor recording and the quality of the recorded signals.Together with a standard for volume and file structure, this International Standard provides for full data interchange betweendata processing systems.2 Conformance2.1 Optical disk cartridgeAn optical disk cartridge sha
