标准摘要
[中文适用范围]： 本国际标准规定了使用不可逆效应、容量为 30 GB 的 WORM（一次写入多次读取）300 毫米光盘盒（ODC）的特性。 此 WORM ODC 使用本质上不可逆的写入效果。 书写标记无法被擦除，并且可以检测到对书写标记的尝试修改。 本国际标准规定 - 一致性测试和参考驱动器的条件； ——墨盒的运行和储存环境； ——盒式磁带的机械、物理和尺寸特性，以便提供数据处理系统之间的机械互换能力； ——磁盘上信息的格式，包括预写和用户写的，包括磁道和扇区的物理配置、纠错码、使用的调制方法； ——磁盘上预先记录的信息的特征； ——磁盘的记录特性，使处理系统能够将数据写入磁盘； ——用户在磁盘上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。 它与卷和文件结构标准一起提供了数据处理系统之间的完整数据交换。 [外文原描述]： This International Standard specifies the characteristics of a 300 mm optical disk cartridge (ODC) of Type WORM (Write Once Read Many) using irreversible effects, with a capacity of 30 Gbytes. This WORM ODC's uses writing effects that are inherently irreversible. Written marks cannot be erased and attempted modifications of the written marks are detectable. This International Standard 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 interchange ability between data processing systems; − the format of the information on the disk, both pre-written and user-written, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used; − the characteristics of the prerecorded information on the disk; − the recording 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.
