标准摘要
[中文适用范围]: 定义 3.81 毫米(0.150 英寸)盒式磁带的特性,以在利用 ISO 7 位编码字符集 (ISO 646) 及其扩展 (ISO 2022) 的信息处理系统之间提供数据交换和物理可互换性。 该盒式磁带为双轮毂共面型,装有 3.81 毫米(0.150 英寸)宽的磁带,使用 31.5 位/毫米(800 bpi)相位编码方法进行数字记录。 磁化方向是磁带的纵向。 [外文原描述]: Defines the characteristics of a 3.81 mm (0.150 in) magnetic tape cassette to provide data interchange and physical interchangeability between information processing systems utilizing the ISO 7-bit coded character set (ISO 646) and its extensions (ISO 2022). The cassette is of the twin hub coplaner type, loaded with 3.81 mm (0.150 in) wide magnetic tape for digital recording using the 31.5 bits per mm (800 bpi) phase encoding method. The direction of magnetization is in the longitudinal direction of the tape.
英文名称Information processing - Information interchange on 3,81 mm (0.150 in) magnetic tape cassette at 4 cpmm (100 cpi), phase encoded at 63 ftpmm (1 600 ftpi)
