This Standard specifies the characteristics of 120 mm optical disks for information interchange between information processing systems and for information storage, called CD-ROM. The optical disk specified by the Standard is of the type in which the information is recorded before delivery to the user and can only be read from the disk. This Standard specifies - some definitions, the environments in which the characteristics of the disk shall be tested and the environments in which it shall be used and stored; - the mechanical, physical, and dimensional characteristics of the disk; - the recording characteristics, the format of the tracks, the error-detecting and the error-correcting characters, and the coding of the information; - the optical characteristics for reading the information. The characteristics are specified for tracks recorded with digital data. According to this Standard, a disk may also contain one or more tracks recorded with digital audio data. Such tracks shall be recorded according to IEC 908.
