scope:

This document specifies the volume and file structure of compact disc read-only memory (CD-ROM) for the interchange of information between users of information processing systems.

This document specifies:

- the attributes of the volume and the descriptors recorded on it;

- the relationship among volumes of a volume set;

- the placement of the 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, this document specifies the functions to be provided within systems which are intended to originate or receive CD-ROM which conform to this document.
