28、data to be written once and read multiple times, using the Sample Servo Format (SSF) tracking method. It specifies - - the conditions for conformance testing and the Reference Drive; the mechanical and physical characteristics of the carridge, so as to provide mechanical interchangeability between d
29、ata processing systems; the format of the information on the disk, both embossed and user-written; the characteristics of the embossed information on the disk; the optical characteristics of the disk, enabling processing systems to write data onto the disk: the minimum qudiy of user-written data on
30、the disk, enabling data processing systems to read data from the disk. Together with the standard for Volume and File Structure, this Standard provides for full data interchange between data processing systems. Interchange involves the ability to write and read data without introducing any error. -
31、- - - Conformance A 300 mm optical disk cartridge is in conformance with this Standard if it meets ail mandatory requirements specified herein. A drive claiming conformance with this Standard shall be able, in the operating environment, to write on any optical disk caruidge which is in conformance w
