Requirements for the processes which are provided within information processing systems, utilizing recorded CD-ROM as the medium of interchange for the functions within systems, which are intended to originate or receive CD-ROM. This Standard is identical with ISO 9660:1988.

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 recorded 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 levels 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 specifies the functions to be provided within systems which are intended to originate or receive CD-ROM which conform to this International Standard.
