本国际标准规定 -一致性测试的条件； -要操作和存储盒的环境； -壳体和盒的机械、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； -盘上的信息的格式，包括压印和用户写入的信息，包括磁道和扇区的物理配置、纠错码和所使用的调制方法； -盘上的压花信息的特征； -所述盘的磁光特性，使得处理系统能够将数据写入到所述盘上； -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读取数据。该国际标准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。

This International Standard specifies - the conditions for conformance testing; - the environments in which the cartridges are to be operated and stored; - the mechanical, physical and dimensional characteristics of the case and of the cartridges, so as to provide mechanical interchangeability between the 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, and the modulation method used; - the characteristics of the embossed information on the disk; - the 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. This International Standard 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.
