GB/T 18140-2000 in English

《GB/T 18140-2000信息技术 130 mm盒式光盘上的数据交换 容量:每盒1 G字节》由TC28（全国信息技术标准化技术委员会）归口，TC28SC23（全国信息技术标准化技术委员会光盘分会）执行，主管部门为国家标准化管理委员会。
本标准规定了具有1G字节容量的130mm盒式光盘（ODC）的特性。本标准定义了两类相关而又有所区别的盒式光盘。R/W型 在盘的全部记录表面采用热磁效应和磁光效应写入，读出和多次擦除数据。W/O型 在盘的全部表面采用热磁效应和磁光效应一次写入，多次读出数据。本标准作了下列规定：--性能测试和参考驱动器的条件；--盒式光盘的操作、存储环境；--盒式光盘和盘盒的机械、物理特性和几何尺寸，以保障信息处理系统的机械可交换性；--盘上模压的或用户写入的信息格式，包括道和扇区的物理位置，纠错码和调制方式；--盘上模压信息的特性；--盘的磁光特性，以使数据处理系统能从盘上读出数据；--盘上用户写入数据的最低质量，以使数据处理系统能从盘上读出数据。本标准提供了光盘驱动器之间的交换。本标准与一个关于盘卷和文卷结构的标准一起提供了数据处理系统之间的全数据交换。交换涉及到不会导致任何错误的写入、读出、擦除的能力。

Scope

This standard specifies the characteristics of a 130 mm optical disc cartridge (ODC) with a capacity of 1 Gbyte. This standard defines two related but distinct types of optical disc cartridges: R/W type uses thermomagnetic and magneto-optical effects on the entire recording surface of the disc to write once, read and erase data multiple times. The W/O type uses thermomagnetic effect and magneto-optical effect on the entire surface of the disk to write once and read data multiple times. This standard specifies the following: --conditions for performance testing and reference drives; --operating and storage environments for disc cartridges; - the mechanical interchangeability of the disc; - the format of information embossed on the disc or written by the user, including the physical location of tracks and sectors, error correction codes and modulation methods; - the characteristics of the information embossed on the disc; - the magnetic properties of the disc optical characteristics, so that the data processing system can read data from the disc; -- the minimum quality of user-written data on the disc, so that the data processing system can read data from the disc; this standard provides exchange. This standard, together with a standard on volumes and file structures, provides for full data exchange between data processing systems. Swapping involves the ability to write, read, and erase without causing any errors.
