标准摘要
[中文适用范围]： 本国际标准规定了容量为 25 GB 或 50 GB 的 120 毫米可重写光盘的机械、物理和光学特性。 它规定了已记录和未记录信号的质量、数据格式和记录方法，从而允许通过此类磁盘进行信息交换。 用户数据可以使用可逆的方法多次写入、读取和覆盖。 符合要求的磁盘被识别为 BD 可重写磁盘。 [外文原描述]： ISO/IEC 30192:2013 specifies the mechanical, physical and optical characteristics of a 120 mm rewritable optical disk with a capacity of 25,0 Gbytes or 50,0 Gbytes. It specifies the quality of the recorded and unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. User data can be written, read and overwritten many times using a reversible method. A confoming disk is identified as a BD Rewritable disk. ISO/IEC 30192:2013 specifies two related but different Types of this disk, the conditions for conformance, the environments in which the disk is to be operated and stored, the mechanical and physical characteristics of the disk, which allow mechanical interchange between data processing systems, the format of the 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 recorded on the disk, which enable data processing systems to read data from the disk. ISO/IEC 30192:2013 provides for interchange of disks between drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.
