适用范围：NOTE — Numeric values in the SI and/or Imperial measurement system in this International Standard may have been rounded and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the twoshouldbeneitherintermixed nor converted. The original design was made using the Imperial measurement system.1 This International Standard specifies the character-istics of a 6,30 mm (0.25 in) magnetic tape cartridge to provide data interchange and physical interchangeability between information processing systems utilizing the ISO 7-bit coded character set (IS0 646)1', its extensions (ISO2022)2) and/or the 8-bit coded character set (IS0 4873)3?.The cartridge is of the twin-hub coplanar type, loaded with a 6,30 mm (0.25 in) magnetic tape for digital recording using the 63 bits per mm (1600 bits per inch) phase-encoding method. The tape is transported between hubs by an internal belt capstan to the external drive. No tape driving or position sensing elements penetrate the cartridge. The direction of magnetization is in the longitudinal direction of the tape.2 This International Standard applies to cartridges used for data interchange. Where it applies for testing only, this is specif ically stated.3 The dimensional units employed in the development of this cartridge were those of the inch system from which metric equivalents were derived using the appropriate conversion method of ISO 3704)
