标准范围

ISO/IEC 23912:2005规定了80mm和120mm DVD可记录磁盘的机械、物理和光学特性，以实现此类磁盘的交换。它规定了预记录、未记录和记录信号的质量、数据格式、信息区格式、未记录区格式和记录方法，从而允许通过此类磁盘进行信息交换。此磁盘被标识为DVD可记录（DVD-R）磁盘。ISO/IEC 23912:2005规定:-标称直径为80 mm和120 mm的圆盘，可为单面或双面；-合规条件；-操作和存储磁盘的环境；-磁盘的机械和物理特性，以便在数据处理系统之间提供机械交换；-未记录磁盘上预记录信息的格式，包括磁道和扇区的物理配置、纠错码和使用的编码方法；-磁盘上数据和记录信息的格式，包括磁道和扇区的物理配置、纠错码和使用的编码方法；-来自磁盘上预记录和未记录区域的信号特征，使数据处理系统能够读取预记录的信息并写入磁盘；和-记录在磁盘上的信号的特征，使数据处理系统能够从磁盘读取数据。ISO/IEC 23912:2005规定了磁盘驱动器之间的磁盘交换。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。

ISO/IEC 23912:2005 specifies the mechanical, physical and optical characteristics of an 80 mm and a 120 mm DVD Recordable disk to enable the interchange of such disks. It specifies the quality of the pre-recorded, unrecorded and the recorded signals, the format of the data, the format of the information zone, the format of the unrecorded zone, and the recording method, thereby allowing for information interchange by means of such disks. This disk is identified as a DVD Recordable (DVD-R) disk.ISO/IEC 23912:2005 specifies:- 80 mm and 120 mm nominal diameter disks that may be either single or double sided;- the conditions for conformance;- the environments in which the disk is to be operated and stored;- the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between data processing systems;- the format of the pre-recorded information on an unrecorded disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used;- the format of the data and the recorded information on the disk, including the physical disposition of the tracks and sectors, the error correcting codes and the coding method used;- the characteristics of the signals from pre-recorded and unrecorded areas on the disk, enabling data processing systems to read the pre-recorded information and to write to the disks; and- the characteristics of the signals recorded on the disk, enabling data processing systems to read the data from the disk.ISO/IEC 23912:2005 provides for interchange of disks between disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.
