scope:

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.
