適用范圍：ISO 8462 specifies the characteristics of a tape cartridge loaded with magnetic tape 6,30 mm (0.25 in) wide intended for digital recording at physical recording densities of 252 ftpmm (6 400 ftpi) and 394 ftpmm (10 000 ftpi). ISO 8462/2 specifies a recording method and a data format in-tended for use in the streaming mode of operation. Two alter-native track formats are specified : — a 4-track format, and — a 9-track format. This part of ISO 8462 specifies the mechanical, physical and magnetic properties of a 6,30 mm (0.25 in) wide magnetic tape cartridge and methods for testing the surface quality of the tape. It also specifies the environmental conditions under which the cartridge shall be tested and operated, and recommends condi-tions for storage. ISO 8462/1 and ISO 8462/2 provide for the physical inter-change of cartridges between data processing systems, anc specify a data format. A labelling standard for tape cartridges used in the streaming mode is under study. The availability of such a labelling standard will provide for full data interchange between data processing systems. NOTE — Numeric values in the SI and/or Imperial measurement system in this part of ISO 8462 may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two should be neither intermixed nor reconverted. The original design was made using the imperial measurement system.
