信息技术 在12.7mm宽、48道盒式磁带上的数据交换 DLT1格式

[中文适用范围]： 指定物理和磁性特性，以实现墨盒的互换性。 还指定了记录信号的质量、格式（称为数字线性磁带 1 (DLT 1)）和记录方法。 [外文原描述]： This International Standard specifies the physical and magnetic characteristics of a 12,7 mm wide, 48-track magnetic tape cartridge, to enable interchangeability of such cartridges. It also specifies the quality of the recorded signals, a format — called Digital Linear Tape 1 (DLT 1) — and a recording method. Together with a labelling standard, e.g. ISO 1001, it allows full data interchange by means of such magnetic tape cartridges.
