National bodies that a
33、re members of IS0 or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other internatio
34、nal organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISOAEC JTC 1. Draft International Standards adopted by the joint technical committee are ci
35、rculated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. International Standard ISO/IEC 15485 was prepared by ECMA (as ECMA-240) and was adopted. under a special “fast-track procedure”, by Joint Technic

38、of 120 mm Optical Disk Cartridges (ODCs) with a capacity of 650 Mbytes using phase change technology. The format for the information on the disk is known as the PD format. The 120 mm ODC has a large degree of commonality with CD-ROM so as to allow drive manufacturers to develop drives which can offe

41、L STANDARD 0 ISOiIEC ISO/IEC 15485: 1997 (E) Information technology - Date interchange on 120 mm optical disk cartridges using phase change PD format - Capacity: 650 Mbytes per cartridge Section 1 - General 1 Scope This International Standard specifies the characteristics of 120 mm Optical Disk Cart
42、ridges (ODCs) with a capacity of 650 Mbytes using Phase Change PD format. This present International Standard specifies two related, but different implementations of such cartridges, viz. Type IUW Provides for data to be written, read and overwritten many times over the whole recording surface of th
43、e disk using the phase change recording and read-out method . Type WORM Provides for data to be written once and read many times over the whole recording surface of the disk using the phase change recording and read-out method. Type R/W and Type WORM are also referred to as “rewritable” and “write-o
44、nce” respectively. This International 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 and physical characteristics of the cartridge, so as to provide mechanical interchange
45、ability between data processing systems; - the format of the information on the disk known as the PD format; including the physical disposition of the tracks and sectors, the error correction codes, and the modulation method used; - the characteristics of the embossed information on the disk; - the
46、phase change recording characteristics of the disk, enabling data 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 International Standard provides for interchange between optical
47、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 cartridge An optical disk cartridge shall be in conformance with this International Standard if it meets the mandatory requiremen
