36、nical Commission) together form a system for worldwide standardization as a whole. National bodies that are 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 techni

37、cal 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 field of information technology, ISO and IEC have established a joint technic

38、al committee, ISO/IEC JTC1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for approval before their acceptance as International Standards. They are approved in accordance with procedures requiring at least75% approval by the national bodies

39、voting. International Standard ISO/IEC10149 was prepared by the European Computer Manufacturers Association (as ECMA-130) 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 IS

Annex F is for information only.vi blankISO/IEC10149:1989(E) BSI 11-1999 1 Introduction In this International Standard clauses1 to3 identify and introduce the contents of the standard; clause4 gives definitions and c

41、lauses5, 6 and7 specify requirements for environments, flammability and material respectively; clauses8 to12 specify the characteristics of the disk; clause12 deals with optical signals; clauses13 to19 describes recording; clauses20 to22 specify the format of the information area. 1 Scope This Inter

42、national Standard specifies the characteristics of120mm optical disks for information interchange between information processing systems and for information storage, called CD-ROM. The optical disk specified by this International Standard is of the type in which the information is recorded before de

43、livery to the user and can only be read from the disk. This International Standard specifies some definitions, the environments in which the characteristics of the disk shall be tested and the environments in which it shall be used and stored; the mechanical, physical, and dimensional characteristic

44、s of the disk; the recording characteristics, the format of the tracks, the error-detecting and the error-correcting characters, and the coding of the information; the optical characteristics for reading the information. The characteristics are specified for tracks recorded with digital data. Accord

45、ing to this International Standard, a disk may also contain one or more tracks recorded with digital audio data. Such tracks shall be recorded according to IEC908. 2 Conformance An optical disk is in conformance with this International Standard if it conforms to all its mandatory requirements. 3 Nor
