24、dardization. National bodies that are members of ISO 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. ISO and IEC technical committees collaborate in fields o
25、f mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in ac
26、cordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International
27、Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent righ
28、ts. ISO/IEC 16448 was prepared by ECMA (as Standard ECMA-267) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval of national bodies of ISO and IEC. This second edition cancels and replaces the fir
29、st edition (ISO/IEC 16448:1999), which has been technically revised. Annexes A to J form a normative part of this International Standard. Annexes K to P are for information only.

30、y disk Section 1 - General 1 Scope This International Standard specifies the mechanical, physical and optical characteristics of a 120 mm, read-only optical disk to enable the interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method
31、, thereby allowing for information interchange by means of such disks. This disk is identified as DVD - Read-Only Disk. This International Standard specifies four related but different Types of this disk (see clause 7), the conditions for conformance, the environments in which the disk is to be oper
32、ated and stored, the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between data processing systems, the format of the information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method
33、 used, the characteristics of the signals recorded on the disk, enabling data processing systems to read the data from the disk. This International Standard provides for interchange of disks between disk drives. Together with a standard for volume and file structure, it provides for full data interc
34、hange between data processing systems. 2 Conformance 2.1 Optical Disk A claim of conformance shall specify the Type of the disk. An optical disk shall be in conformance with this International Standard if it meets the mandatory requirements specified for its Type. 2.2 Generating system A generating
35、system shall be in conformance with this International Standard if the optical disk it generates is in accordance with 2.1. 2.3 Receiving system A receiving system shall be in conformance with this International Standard if it is able to handle all four Types of optical disk according to 2.1. 3 Norm

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements ba
37、sed on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of curre

39、dhesive layer A layer of adhesive material bonding together the two parts of the disk. 4.2 Channel bit The elements by which, after modulation, the binary values ZERO and ONE are represented on the disk by pits. 4.3 Clamping Zone The annular part of the disk within which a clamping force is applied
40、by a clamping device. 4.4 Digital Sum Value (DSV) The arithmetic sum obtained from a bit stream by allocating the decimal value 1 to bits set to ONE and the decimal value -1 to bits set to ZERO. 4.5 Disk Reference Plane A plane defined by the perfectly flat annular surface of an ideal spindle onto w
41、hich the Clamping Zone of the disk is clamped, and which is normal to the axis of rotation. 4.6 Dual Layer disk A optical disk with one or two entrance surface(s), in which each entrance surface gives access to a different pair of recorded layers. 4.7 Dummy substrate A layer which may be transparent
42、 or not, provided for the mechanical support of the disk and/or of a recorded layer. 4.8 Entrance surface The surface of the disk onto which the optical beam first impinges. 4.9 Optical disk A disk that accepts and retains information in the form of pits in a recorded layer that can be read by an op
43、tical beam. 4.10 Physical sector number A serial number allocated to physical sectors on the disk. 4.11 Read-only disk An optical disk in which the information has been recorded when manufacturing the disk. The information cannot be modified and can only be read from the disk. 4.12 Recorded layer A
44、layer of the disk on, or in, which data is recorded. 4.13 Reed-Solomon code An error detection and/or correction code for the correction of errors. 4.14 Reserved field A field set to all ZEROs unless otherwise stated, and reserved for future standardization. 4.15 Sector The smallest part of a track
45、in the Information Zone that can be accessed independently of other addressable parts. 4.16 Single Layer disk An optical disk with one or two entrance surface(s), in which each entrance surface gives access to a different recorded layer. 4.17 Spacer In the case of Dual Layer disks, the transparent l

48、is rounded off to the least significant digit of the corresponding specified value. For instance, it implies that a specified value of 1,26 with a positive tolerance of + 0,01 and a negative tolerance of - 0,02 allows a range of measured values from 1,235 to 1,275. Numbers in decimal notations are r
49、epresented by the digits 0 to 9. Numbers in hexadecimal notation are represented by the hexadecimal digits 0 to 9 and A to F in parentheses. The setting of bits is denoted by ZERO and ONE. Numbers in binary notations and bit patterns are represented by strings of digits 0 and 1, with the most significant bit shown to the left. Negative values of numbers in binary notation are given as Twos complement. In each field the data is recorded so that the most significant byte (MSB), identified as Byte 0, is recorded first and
