中文标准名称：信息处理．未记录的12,7毫米（0.5）宽磁带信息交换．32 ftpmm （800tpi）NRZ1，126 ftpmm （3200 TPI）相编码和356 ftpmm（9042ftpi）NRZ1
英文标准名称：Information processing - Unrecorded 12,7 mm (0.5 in) wide magnetic tape for information interchange - 32 ftpmm (800tpi) NRZ1, 126 ftpmm (3 200 tpi) phase encoded and 356 ftpmm (9 042ftpi) NRZ1

适用范围：This International Standard specifies the characteristics of 12,7 mm (0.5 in) wide magnetic tape with reel, to enable magnetic and mechanical interchangeability of such tape be-tween information processing systems.This International Standard applies solely to magnetic tape for digital recording using the NRZ1 method of recording at 32 and 356 ftpmm (800 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.NOTE — Numeric values in the SI and/or Imperial measurement system in this International Standard 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.
