标准范围

ISO/IEC 11976:2008规定了130 mm光盘盒（ODC）的机械、物理和光学特性，该光盘盒采用热光相变效应来实现这些光盘之间的数据交换。ISO/IEC 11976:2008规定了两种类型的光盘。类型RW（可重写）提供了在盘的记录表面上多次写入、读取和擦除数据。类型WORM（写一次读多次）提供了数据一旦被写入就被多次读取。这种类型使用一次写入多次读取的记录材料（写入的标记不能被擦除，并且对写入的标记的尝试修改是可检测的）。可以在WORM类型磁盘上执行多会话（增量写入操作）记录。磁盘是双面的，每面标称容量为30,0 GB，盒式磁带（双面）的标称容量为60,0 GB。ISO/IEC 11976:2008规定了以下内容:一致性测试的条件和参考驱动器；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 11976:2008规定了光盘驱动器之间的互换。与卷和文件结构的标准一起，它提供了数据处理系统之间的完全数据交换。

ISO/IEC 11976:2008 specifies the mechanical, physical, and optical characteristics of a 130 mm optical disk cartridge (ODC) that employs thermo-optical Phase Change effects to enable data interchange between such disks.

ISO/IEC 11976:2008 specifies two types of disk.

• Type RW (Rewritable) provides for data to be written, read and erased many times over the recording surfaces of the disk.


• Type WORM (Write Once Read Many) provides for data once written to be read a multiplicity of times. This type uses a Write Once Read Many times recording material (written marks cannot be erased and attempted modifications of the written marks are detectable). Multisession (incremental write operations) recording may be performed on Type WORM disks.

The disk is two-sided with a nominal capacity of 30,0 Gbytes per side and the cartridge (two sides) provides a nominal capacity of 60,0 Gbytes.

ISO/IEC 11976:2008 specifies the following:

• 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-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 11976:2008 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.
