英文标准名称:Information technology - Unrecorded 12,7 mm (0,5 in) wide magnetic tape for information interchange - 32 ftpmm (800 ftpi) NRZ1, 126 ftpmm (3 200 ftpi) phase encoded and 356 ftpmm (9 042 ftpi) NRZ1

适用范围:This International Standard specifies the character-istics of 12,7 mm (0,5 in) wide magnetic tape with reel, to enable magnetic and mechanical inter-changeability of such tape between information processing systems. This International Standard applies solely to mag-netic tape for digital recording using the NRZ1 method of recording at 32 ftpmm and 356 ftpmm (800 ftpi and 9 042 ftpi) or the phase-encoded method of recording at 126 ftpmm (3 200 ftpi) in which the direction of magnetization is nominally longitudinal. Some numeric values in the SI and/or Imperial measurement system in this International Standard 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 re-converted. The original design was made using the Im-perial measurement system.
