标准范围

ISO/IEC 17346:2005定义了90mm光盘盒(ODC)的特性，每个盒的容量为1.3 GB。它只为这种盒式磁带的2 048字节扇区指定类型R/W。R/W型利用热磁和磁光效应在盘的整个记录表面上多次写入、读取和擦除数据。它也被称为“完全可重写”。ISO/IEC 17346:2004仅提供2 048字节的扇区。磁盘上的所有扇区大小相同。ISO/IEC 17346:2005规定:一致性测试的条件和参考驱动器；将操作和存储盒的环境；盒的机械和物理特性，以便在数据处理系统之间提供机械互换能力；磁盘上信息的格式，包括浮雕和用户书写；包括轨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；磁盘的磁光特性，使得处理系统能够将数据写入磁盘；用户写入磁盘的数据的最低质量，使数据处理系统能够从磁盘读取数据。ISO/IEC 17346:2005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 17346:2005 defines the characteristics of 90 mm Optical Disk Cartridges (ODC) with a capacity of 1,3 GB per cartridge. It specifies only Type R/W for 2 048-byte sectors of such cartridges.

Type R/W provides for data to be written, read and erased many times over the entire recording surface of the disk using the thermo-magnetic and magneto-optical effects. It is also referred to as "fully rewritable". ISO/IEC 17346:2004 provides for 2 048-byte sectors only. All sectors on a disk are of the same size.

ISO/IEC 17346:2005 specifies:

• the conditions for conformance testing and the Reference Drive;
• the environments in which the cartridges are to be operated and stored;
• the mechanical and physical characteristics of the cartridge, so as to provide mechanical interchange ability 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, 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.
