标准范围

ISO/IEC 22051:2002规定了磁带盒的物理和磁性特性，使用12，65mm宽的磁带，以便在驱动器之间提供这种磁带盒的物理互换。它还规定了记录信号的质量、记录方法和记录格式，从而允许通过这种盒式磁带在驱动器之间进行数据交换。线性记录格式称为超级数字线性磁带1（SDLT 1），有448个轨道。它结合了磁性和光学技术，称为激光制导磁记录（LGMR）。带的后表面呈现光学检测的伺服标记。该格式源自DLT格式。它提供110 GB未压缩用户数据的容量，或通常220 GB压缩用户数据的容量。连同卷和文件结构的标准，本文档提供了数据处理系统之间的完全数据交换。

ISO/IEC 22051:2002 specifies the physical and magnetic characteristics of magnetic tape cartridges, using magnetic tape 12,65 mm wide so as to provide physical interchange of such cartridges between drives. It also specifies the quality of the recorded signals, the recording method and the recorded format, thereby allowing data interchange between drives by means of such cartridges.

The linearly recorded format, called Super Digital Linear Tape 1 (SDLT 1), has 448 tracks. It uses a combination of magnetic and optical technologies known as Laser-Guided Magnetic Recording (LGMR). The back surface of the tape presents optically detected servo marks.

The format is derived from the DLT Format. It provides for a capacity of 110 Gbytes of uncompressed user data, or typically 220 Gbytes of compressed user data.

Together with a standard for volume and file structure this document provides for full data interchange between data processing systems.
