11、ation Systems Technology Standards Committee, is identical with ISO 9660:1988 “Information processing Volume and file structure of CD-ROM for information interchange”, published by the International Organization for Standardization (ISO). Terminology and conventions. The text of the international st
12、andard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. Wherever the words “International Standard” appear, referring
13、 to this standard, they should be read as “British Standard”. The Technical Committee has reviewed the provisions of ISO 1539 and ISO 2375, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport
14、to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International standardCorresponding British Standard ISO 646

General 1 Scope and field
18、of application This International Standard specifies the volume and file structure of compact read only optical disks (CD-ROM) for the interchange of information between users of information processing systems. This International Standard specifies the attributes of the volume and the descriptors re
19、corded on it; the relationship among volumes of a volume set; the placement of files; the attributes of the files; record structures intended for use in the input or output data streams of an application program when such data streams are required to be organized as sets of records; three nested lev
20、els of medium interchange; two nested levels of implementation; requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems, utilizing recorded CD-ROM as the medium of interchange; for this purpose it spe
21、cifies the functions to be provided within systems which are intended to originate or receive CD-ROM which conform to this International Standard. 2 Conformance 2.1 Conformance of a CD-ROM A CD-ROM shall be in conformance with this International Standard when all information recorded on it conforms
22、to the requirements of section 2 of this International Standard. A statement of conformance shall identify the lowest level of interchange to which the contents of the CD-ROM conform. A prerequisite to such conformance is conformance of the CD-ROM to a standard for recording (see 4.15). 2.2 Conforma
23、nce of an information processing system An information processing system shall be in conformance with this International Standard if it meets the requirements specified in sections 2 and 3 of this International Standard either for an originating system, or for a receiving system, or for both types o
24、f system. A statement of conformance shall identify which level of these requirements can be met by the system. 3 References ISO 646, Information processing ISO 7-bit coded character set for information interchange.
