This International Standard specifies the volume and file struc-ture of compact read only optical disks (CD-ROM) for the inter-change 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 out-put 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, utiliz-ing 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.
