3、 Optical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC JTC1/SC23 toward the development of International Standards for optical disks with a diameter of 80 mm, 90 mm, 120 mm, 130 mm, 300 mm and 356 mm. Numerous standards have b

This E
43、cma Standard specifies two types, viz. - Type RW (Rewritable) provides for data to be written read and erased many times over the recording surfaces of the disk. - Type WORM (Write Once Read Many) provides for data once written to be read a multiplicity of times. This type shall use a Write Once Rea
44、d Many times recording material (written marks cannot be erased and attempted modifications of the written marks are detectable). Multisession (incremental write operations) recording may be performed on Type WORM disks. The disk shall be two-sided with a nominal capacity of 15,0 Gbytes per side and
45、 the cartridge (two sides) shall provide a nominal capacity of 30,0 Gbytes. This Ecma Standard specifies - the conditions for conformance testing and the Reference Drive; - the environments in which the cartridges are to be operated and stored; - the mechanical, physical and dimensional characterist
46、ics of the cartridge so as to provide mechanical interchangeability between data processing systems; - the format of the information on the disk, both embossed and user-written, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used; - t
47、he characteristics of the embossed information on the disk; - the thermo-optical characteristics of the disk, enabling processing systems to write data onto the disk; - the minimum quality of user-written data on the disk, enabling data processing systems to read data from the disk. This Ecma Standa
48、rd provides for interchange between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems. 2 Conformance 2.1 Optical disk An ODC shall be in conformance with this Ecma Standard if it meets all mandatory requ
49、irements specified therein. A claim of conformance with this Ecma Standard shall specify the Type, RW, WORM, implemented. 2.2 Generating system A claim of conformance with this Ecma Standard shall specify which Type(s) is (are) supported. A system generating an ODC for interchange shall be in conformance with this Ecma Standard if it meets the mandatory requirements of this Ecma Standard for the Type(s) supported. - 2 -2.3 Receiving system A claim of conformance with this Ecma Standard shall specify which Type(s) is (are) supported.
