The ECMA work resulted in two ECMA Standards in June 1993: ECMA-189 Information Interchange on 300 rnm Optical Disk Cartridges of the Write Once,
5、 Read Multiple (WORM) Type Using the SSF Method JXMA-190 Information Interchange on 300 mm Optical Disk Cartridges of the Write Once, Read Multiple (WORM) Type Using the CCS Method Both standards have been registered in 1993 as ISO/IEC CD 13614 and CD 13403, respectively. The standards are identical

29、3 0018020 526 Section 1 - General 1 Scope This ECMA Standard specifies the characteristics of 300 mm optical disk cartridges (OW) of the WORM type providing for embossed information and for data to be written once and read multiple times using the Continuous Composite Servo (CCS) tracking method. It
30、 specifies - - the conditions for conformance testing and the reference drive; the mechanical and physical characteristics 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; the
31、characteristics of the embossed information on the disk; the 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. Together with the standard for
32、 Volume and File Structure, this Standard provides for full data interchange between data processing systems. Interchange involves the ability to write and read data without introducing any error. - - - - 2 Conformance A 300 mm optical disk cartridge is in conformance with this Standard if it meets
33、all mandatory requirements specified herein. A drive claiming conformance with this Standard shall be able, in the operating environment, to write on any optical disk cddge which is in conformance with this Standard and to read any such optical disk cartridge which has been written with any drive in
34、 conformance with this Standard. A drive shall not claim conformance if it cannot accept the full range of media conforming to the Standard. 3 References ECMA-129 : 1988, Safety of Information Technology Equipment, including Electrical Business Equipment. 4 Definitions For the purpose of this Standa

Conventions Representation of numbers - A measured value is rounded off to the least significant digit of the corresponding specified value. It i
46、mplies 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 less than 1,275. Letters and digits in parentheses represent numbers in hexadecimal notation. The setting of a bit is denoted by ZERO or ONE. Nu
47、mbers in binary notation and bit combinations are represented by strings of ZEROS and ONES. Numbers in binary notation and bit combinations are shown with the most significant bit to the left. Negative values of numbers in binary notation are given in TWOS complement. In each field the data is recor
48、ded so that the most significant byte (byte O) is recorded first. Within each byte the least significant bit is numbered O and is recorded last, the most significant bit (numbered 7 in an %bit byte) is recorded first. This order of recording applies also to the data input of the Error Detection and
49、Correction circuits and to their output. - - - - - - Names The names of entities, e.g. specific tracks, fields, etc., are given with a capital initial.
