本文件定义了声称符合LTFS要求的交换媒体的LTFS格式要求。这些要求规定为媒体上数据块和文件标记的大小和顺序、特殊数据结构（LTFS标签和LTFS索引）的内容和形式、分区标签的内容和MAM参数的使用。 LTFS格式的数据内容（而非物理介质）应在声称符合该格式的所有数据存储系统之间可互换。物理媒体交换取决于物理媒体和使用中的媒体访问设备的兼容性。 注意:本文档不包含构建LTFS结构的说明或磁带命令序列。

This document defines the LTFS Format requirements for interchanged media that claims LTFS compliance. Those requirements are specified as the size and sequence of data blocks and file marks on the media, the content and form of special data constructs (the LTFS Label and LTFS Index), and the content of the partition labels and use of MAM parameters. The data content (not the physical media) of the LTFS format shall be interchangeable among all data storage systems claiming conformance to this format. Physical media interchange is dependent on compatibility of physical media and the media access devices in use. NOTE: This document does not contain instructions or tape command sequences to build the LTFS structure.
