标准范围

ISO/IEC 22092:2002规定了130 mm光盘盒（ODC）的机械、物理和光学特性，该光盘盒采用热磁和磁光效应来实现这些光盘之间的数据交换。类型R/W提供了在盘的记录表面上多次写入、读取和擦除数据。类型WO提供了一旦写入的数据被多次读取。不得删除或修改数据。可以在类型WO盘上执行多会话(增量写入操作)记录。如果在A和B两面都记录，则磁盘应为同一类型。每侧的标称容量应为4.58 GB，与类型无关。该格式指定了两个扇区大小，并允许模拟另外两个大小。ISO/IEC 22092:2002规定了一致性测试和参考驱动器的条件；将操作和存储盒的环境；盒的机械、物理和尺寸特性，以便在数据处理系统之间提供机械互换性；盘上信息的格式，包括浮雕和用户写入的，包括磁道和扇区的物理配置、纠错码、使用的调制方法；盘上的压花信息的特征；盘的热磁和磁光特性，使得处理系统能够将数据写入盘上；磁盘上用户写入数据的最低质量，使数据处理系统能够从磁盘中读取数据。ISO/IEC 22092:2002规定了光盘驱动器之间的互换。它与卷和文件结构的标准一起提供了数据处理系统之间的完全数据交换。

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.
