标准摘要
[中文适用范围]： 该国际标准规定了 12.7 毫米宽、448 磁道盒式磁带的物理和磁性特性，以实现此类盒式磁带在驱动器之间的物理互换性。 它还指定了记录信号的质量、一种称为超级数字线性磁带 1 (SDLT 1) 的格式以及一种记录方法，从而允许驱动器之间进行数据交换。 与标签标准（例如用于磁带标签的 ISO 1001）一起，它允许通过此类磁带盒进行完整的数据交换。 [外文原描述]： 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.
