3、(Write OnceRead Many) Using IrreversibleEffects - Capacity: 5,2 Gbytesper Cartridge.Brief HistoryTechnical Committee ECMA TC31 for Optical Disk Cartridges (ODCs) was set up in 1984. The Committee made majorcontributions to ISO/IEC JTC1/SC23 to the development of standards for 90 mm, 120 mm, 130 mm a
4、nd 300 mm ODCs, andprovided camera-ready copies for most International Standards for ODCs. ECMA has published the following ECMAStandards for ODCs, most of them have been adopted by ISO/IEC under the fast-track procedure.ECMA-130 (1988) Data Interchange on Read-only 120 mm Optical Data Disks (CD-ROM

9、tandard specifies an ODC of Type WORM which cannot be erased or over-written without detection. Inorder to clearly differentiate this type from Type WO where a microcode is used to protect against undetectable over-writing ofM.O. disks, the term “irreversible effects“ has been introduced in the titl
10、e. The ODC specified by this ECMA Standard is basedon International Standard ISO/IEC 15286 for an ODC available in seven different types. The ODC of Type WORM accordingto this ECMA Standard is built upon the same MO base and retains all physical and embossed characteristics of ISO/IEC15286, but diff
