标准范围

ISO/IEC 17345:2006规定了130mm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。它指定了两种类型:类型RW（可重写）提供了在磁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。

ISO/IEC 17345:2006 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.

It specifies two types:

• 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.
