标准范围

本文件规定了容量为100,0千兆字节、128,0千兆字节或200,0千兆字节的120毫米可记录光盘的机械、物理和光学特性。它规定了记录和未记录信号的质量、数据的格式和记录方法，从而允许通过这种盘进行信息交换。用户数据可以使用不可逆的方法进行一次写入和多次读取。该盘被识别为BD可记录盘。本文件规定了以下内容:-该盘的三种相关但不同类型；-符合性的条件；-磁盘将被操作和存储的环境；-盘的机械和物理特性，以便在数据处理系统之间提供机械互换；-盘上信息的格式，包括磁道和扇区的物理配置；-所使用的纠错码和编码方法；-记录在盘上的信号的特性，使得数据处理系统能够从盘读取数据。本文档规定了磁盘驱动器之间的磁盘互换。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。

This document specifies the mechanical, physical and optical characteristics of a 120 mm recordable optical disk with a capacity of 100,0 Gbytes, 128,0 Gbytes or 200,0 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 once and read many times using a non-reversible method. This disk is identified as BD recordable disk.
This document specifies the following:
- three 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, so as to provide 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, enabling data processing systems to read the data from the disk.
This document 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.
