49、ptical effects. A part or all of the optical disk may be pre-recorded and be reproduced by stamping or other means. Thisinformation is read without recourse to the magneto-optical effect. This International Standard together with a standard for volume and file structure provides for full data interchange between data processing systems. Interchange involves the ability to write, read and erase data without introducing any error. Section 1. General 1 Scope This Internat
