ISO/IEC 13346规定了音量和启动块识别的格式和相关系统要求， 卷结构、文件结构和记录结构，用于媒体用户之间的信息交换 信息处理系统。 记录媒体时，应将扇区的记录视为可按任何顺序进行。 注1:介质不限于一种类型；介质类型可以是一次写入，也可以是只读，或者 可重写的，或这些类型的组合。 ISO/IEC 13346由以下五部分组成: 第1部分:概述 第2部分:音量和启动块识别 第3部分:卷结构 第4部分:文件结构 第5部分:记录结构 附录A——ICB策略是ISO/IEC 13346-4的一部分。 ISO/IEC 13346的本部分规定了卷结构的格式和相关系统要求 具体说明: 卷的属性和记录在卷上的描述符； 卷集的卷之间的关系； 卷分区的属性； 逻辑卷的属性及其上记录的描述符； 中等程度的交流； 信息处理系统中提供的流程要求 不同系统之间交换的信息；为此，它指定了要执行的功能 在系统内提供，旨在产生或接收符合本部分要求的介质 ISO/IEC 13346。

ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume structure, file structure and record structure for the interchange of information on media between users of information processing systems. The media shall be recorded as if the recording of sectors may be done in any order. Note 1 - The medium is not restricted to being of only one type; the type of medium may be either write once, or read only, or rewritable, or a combination of these types. ISO/IEC 13346 consists of the following five Parts: Part 1: General Part 2: Volume and Boot Block Recognition Part 3: Volume Structure Part 4: File Structure Part 5: Record Structure Annex A - ICB Strategies, is part of ISO/IEC 13346-4. This part of ISO/IEC 13346 specifies a format and associated system requirements for volume structure by specifying: the attributes of a volume and the descriptors recorded on it; the relationship among volumes of a volume set; the attributes of a partition of a volume; the attributes of a logical volume and the descriptors recorded on it; levels of medium interchange; requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems; for this purpose, it specifies the functions to be provided within systems which are intended to originate or receive media which conform to this part of ISO/IEC 13346.
