Specifies the characteristics of 300 mm optical disk cartridges (ODC) of the WORM type providing for embossed information and for data to be written once and read multiple times, using the Sample Servo Format (SSF) tracking method. Together with the standard for Volume and File Structure, it provides for full data interchange between data processing systems. Interchange involves the ability to write and read data without introducing any error.
