Explains the characteristics of a tape cartridge using 6.30 mm wide magnetic tape for data interchange between data processing systems. Specifies the quality of the recorded signals, and the track format to be used on a 6,30 mm magnetic tape cartridge recorded at 252 ftpmm using IMFM recording and the start/stop mode of operation. Gives the dimensional, physical and magnetic characteristics of the cartridge, and the track layout.

ISO 8063 specifies the characteristics of a tape cartridge using 6,30 mm (0.25 in) wide magnetic tape for data interchange between data processing systems.
ISO 8063-2 specifies the quality of the recorded signals, and the track format to be used on a 6,30 mm (0.25 in) magnetic tape cartridge recorded at 252 ftpmm (6 400 ftpi) using IMFM recording and the start/stop mode of operation. This part of ISO 8063 specifies the dimensional, physical and magnetic characteristics of the cartridge, and the track layout.
Together with the labelling scheme specified in ISO 4341, ISO 8063-1 and ISO 8063-2 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 8063 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.
ISO 8063 applies to cartridges used for data interchange. Where it applies for testing only, this is specifically stated.
