2、ta Interchange on 130 mm Rewritable and Write Once Read Many Ultra Density Optical (UDO) Disk Cartridges Capacity: 60 Gbytes per Cartridge Second Generation Standard ECMA-380 1st Edition / December 2007 Brief history Ecma Technical Committee TC31 was established in 1984 for the standardization of Op
3、tical Disks and Optical Disk Cartridges (ODC). Since its establishment, the Committee has made major contributions to ISO/IEC JTC 1/SC 23 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 be
4、en developed by TC31 and published by Ecma, almost all of which have also been adopted by ISO/IEC under the fast-track procedure as International Standards. The present Standard is the Second Generation of the UDO Standard initially published (1stEdition) as ECMA-350 in 2003 and as ISO/IEC 17345 in
5、2004. This Ecma Standard has been adopted by the General Assembly of December 2007. - i - Table of contents Section 1 General 1 1 Scope 1 2 Conformance 1 2.1 Optical disk 1 2.2 Generating system 1 2.3 Receiving system 1 2.4 Compatibility statement 2 3 Reference 2 4 Definitions 2 4.1 band 2 4.2 case

34、 specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-optical Phase Change effects to enable data interchange between such disks. This Ecma Standard specifies two types, viz. Type RW (Rewritable) provides for data to be written
35、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 Read Many times recording material (written marks cannot be erased and attempted modifications of t
36、he 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 30,0 Gbytes per side and the cartridge (two sides) shall provide a nominal capacity of 60,0 Gbytes. This Ecma Standard s
37、pecifies 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 characteristics of the cartridge so as to provide mechanical interchangeability between data processing systems; t
38、he 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; the characteristics of the embossed information on the disk; the thermo-optical characteristics of the disk
39、, 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 Standard provides for interchange between optical disk drives. Together with a standard for volume and file structur
40、e, 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 requirements specified therein. A claim of conformance with this Ecma Standard shall specify the Type, RW or WORM,
41、 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) s
42、upported. 2.3 Receiving system A claim of conformance with this Ecma Standard shall specify which Type(s) is (are) supported. - 2 - A system receiving an ODC for interchange shall be in conformance with this Ecma Standard if it is able to process any recording made on the cartridge according to 2.1
43、on the Type(s) specified. 2.4 Compatibility statement A claim of conformance with this Ecma Standard shall include a statement listing any other Optical Disk Cartridge Standard supported by the system for which conformance is claimed. This statement shall specify the number of the Standard(s), inclu
44、ding, where appropriate, the ODC Type(s), and whether support includes reading only or both reading and writing. 3 Reference The following Standards contain provisions, which through reference in this text, constitute provisions of this Ecma Standard.
