标准摘要
[中文适用范围]： ISO/IEC 13346 规定了用于信息处理系统的用户之间在介质上交换信息的卷和引导块识别、卷结构、文件结构和记录结构的格式和相关系统要求。 介质的记录应如同扇区的记录可以按任何顺序进行一样。 注1——介质不限于只有一种类型；介质的类型可以是一次写入、只读、可重写、或这些类型的组合。 本国际标准由以下五个部分组成： 第 1 部分：通用 第 2 部分：卷和引导块识别 第 3 部分：卷结构 第 4 部分：文件结构 第 5 部分：记录结构 附件 A - ICB 策略，是 ISO 本部分的一部分/IEC 13346。 ISO/IEC 13346 的这一部分通过指定以下内容指定了文件结构的格式和相关系统要求： ——文件的放置； ——文件的属性； ——逻辑卷的文件之间的关系； ——中等交换水平； ——对信息处理系统内提供的流程的要求，以使信息能够在不同系统之间交换；为此，它指定了在旨在发起或接收符合 ISO/IEC 13346 本部分的媒体的系统内提供的功能。 [外文原描述]： 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. This International Standard 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 this part of ISO/IEC 13346. This part of ISO/IEC 13346 specifies a format and associated system requirements for file structure by specifying: - the placement of files; - the attributes of the files; - the relationship among files of a logical volume; - 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.
