Specifies the characteristics of a case for use with the 120 mm and 80 mm DVD-RAM disks specified in Standard ECMA 330. Specifies: - the environments in which the cases are to be operated and stored; - the dimensional and mechanical characteristics of the case, so as to provide mechanical interchangeability between data processing systems. Provides for mechanical interchange between optical disk drives.
