标准范围

ISO/IEC 16449规定了80mm只读光盘的机械、物理和光学特性，以实现这种光盘的互换。它规定了记录信号的质量、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。该盘被识别为DVD只读盘。ISO/IEC 16449规定了该盘的四种相关但不同的类型、一致性条件、盘要操作和存储的环境、盘的机械和物理特性，以便在数据处理系统之间提供机械交换、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、盘上记录的信号的特性，使得数据处理系统能够从盘上读取数据。ISO/IEC 16449提供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。

ISO/IEC 16449 specifies the mechanical, physical and optical characteristics of a 80 mm, read-only optical disk to enable the interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. This disk is identified as DVD - Read-Only Disk.

ISO/IEC 16449 specifies

• four 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.
