National bodies that are members of

27、 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 international organizat

28、ions, 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 circulated to n

29、ational 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 Technical Committee

30、ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of IS0 and IEC. Annexes A to J form an integral part of this International Standard. Annexes K to Q are for information only. . . . VIII OISO/IEC ISO/IEC 15485:19!w (E) Introduction This International Standard sp

31、ecifies the characteristics 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 d

32、evelop drives which can offer read compatibility with CD-ROM as defined in ISO/IEC 10149. This International Standard specifies two types of ODCs (Type R/W and Type WORM) both of which are intended for use in dual-function optical disk drives with the capacility to handle both the 120 mm ODCs and CD

33、-ROM disks such as those conforming to ISO/IEC 10149. ix INTERNATIONAL 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 Internation

34、al Standard specifies the characteristics of 120 mm Optical Disk Cartridges (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, r

35、ead and overwritten many times over the whole recording surface of the 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. Typ

36、e R/W and Type WORM are also referred to as “rewritable” and “write-once” 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 char

37、acteristics of the cartridge, so as to provide mechanical interchangeability 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;

38、- the characteristics of the embossed information on the disk; - the 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.

39、This International Standard 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 cartridge An optical disk cartridge shall be in conformance

40、with this International Standard if it meets the mandatory requirements specified herein for its Type. 2.2 Generating system A generating system shall be in conformance with this International Standard if the ODC it generates is in accordance with 2.1. 2.3 Receiving system A receiving system shall b

41、e in conformance with this International Standard if it is able to handle an ODC according to 2.1. 2.4 Compatibility statement A claim of conformance by a generating or receiving system with this International Standard shall include a statement listing any other International Optical Disk Cartridge

42、Standard(s) supported. This statement shall specify the number of the standard(s), including, where appropriate, the ODC type(s) and whether support includes reading only or both reading and writing. 3 Normative reference The following standard contains provisions which, through reference in this te

43、xt, constitute provisions of this International Standard. At the time of publication, the edition indicated was valid. All standards are subjected to revision, and parties to ISO/IEC 15485:1997 (E) OISOAEC agreements based on this International Standard are encouraged to investigate the possibility

44、of applying the most recent edition of the standard listed below. Members of IEC and IS0 maintain registers of currently valid International Standard. IEC 950: 199 1, Safety of information technology equipment. 4 Definitions For the purposes of this International Standard, the following definitions

46、ects the disk and facilitates disk interchange. Channel bit: The elements by which the binary values ZERO and ONE are represented on the disk by either a space or a mark. NOTE - In this International Standard each input bit is represented by two Channel bits. Their sequence depends on that of the in

47、put bits. 4.5 4.6 4.7 4.8 4.9 4.10 4.11 4.12 4.13 4.14 4.15 4.16 4.17 Clamping Zone: The annular part of the disk within which the clamping force is applied by the clamping device. control track: A track containing the information on media parameters and format necessary for writing and reading the

48、remaining tracks of the optical disk. Cyclic Redundancy Check (CRC): A method for detecting errors in data. defect management: A method for handling the defective areas on the disk. disk reference plane: A plane defined by the perfectly flat annular surface of an ideal spindle onto which the clampin

49、g zone of the disk is clamped, and which is normal to the axis of rotation. embossed mark: A mark so formed as to be unalterable by optical means. entrance surface: The surface of the disk onto which the optical beam first impinges. Error Correction Code (ECC): An error-detecting code designed to correct certain kinds of errors in data. field: A subdivision of a sector. format: The arrangement of information on the disk. interleaving: The process of allocating the physical sequence of units of data so as to render the data more immune to burst errors. l
