3、(Write Once ReadMany) Using Irreversible Effects- Capacity: 30 Gbytes perCartridgeBrief HistoryTechnical Committee ECMA TC31 for Optical Disk Cartridges (ODCs) was set up in 1984. The Committee mademajor contributions to ISO/IEC JTC1/SC23 to the development of standards for 90 mm, 120 mm, 130 mm and
4、300 mm ODCs, and provided camera-ready copies for most International Standards for ODCs. The following ECMAStandards for WORM (Write Once Read Multiple) ODCs have been published and have been adopted by ISO/IECunder the fast-track procedure.ECMA-153 (1991) Information Interchange on 130 mm Optical D
