信息技术.在130mm盒式磁光盘的数据交换.容量.9,1千兆字节

[中文适用范围]： 该国际标准规定了 130 毫米光盘盒 (ODC) 的机械、物理和光学特性，该光盘盒利用热磁和磁光效应实现此类磁盘之间的数据交换。 本国际标准指定了两种类型，即。 R/W 类型允许在磁盘的记录表面上多次写入、读取和擦除数据。 WO 类型允许数据一旦写入即可多次读取。 数据不得被删除或修改。 可以在 WO 类型磁盘上执行多会话（增量写入操作）记录。 如果 A 面和 B 面均进行记录，则磁盘应为相同类型。 无论类型如何，每一面的标称容量均为 4,58 GB。 该格式指定两个扇区大小并允许模拟另外两个大小。 本国际标准规定 - 一致性测试和参考驱动器的条件； ——墨盒的运行和储存环境； ——盒的机械、物理和尺寸特性，以提供数据处理系统之间的机械互换性； ——磁盘上信息的格式，包括压印的和用户写入的，包括磁道和扇区的物理配置、纠错码、使用的调制方法； ——盘上压印信息的特征； ——磁盘的热磁和磁光特性，使处理系统能够将数据写入磁盘； ——用户在磁盘上写入数据的最低质量，使数据处理系统能够从磁盘读取数据。 该国际标准规定了光盘驱动器之间的互换。 它与卷和文件结构标准一起提供了数据处理系统之间的完整数据交换。 [外文原描述]： ISO/IEC 22092:2002 specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-magnetic and magneto-optical effects to enable data interchange between such disks. ISO/IEC 22092:2002 specifies two Types, viz. Type R/W provides for data to be written, read and erased many time over the recording surface(s) of the disk. Type WO provides for data once written to be read a multiplicity of times. Data shall not be erased nor amended. Multisession (incremental write operations) recording may be performed on type WO disks. The disk shall be of the same Type if recorded on both sides, A and B. Each side shall have a nominal capacity of 4,58 Gbytes, irrespective of the Type. The format specifies two sector sizes and allows for emulation of two further sizes. ISO/IEC 22092:2002 specifies the conditions for conformance testing and the Reference Drive;the environments in which the cartridges are to be operated and stored;the mechanical, physical and dimensional 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, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used;the characteristics of the embossed information on the disk;the thermo-magnetic and magneto-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. ISO/IEC 22092:2002 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.
