BS 7023-1:1988

This standard BS 7023-1:1988 Guide to construction and use of 130 mm (5.25 in) flexible disk cartridges for data interchange using modified frequency modulation recording at 7958 ftprad, 3.8 tpmm (96 tpi) on both sides is classified in these ICS categories:

• 35.220.21 Magnetic disks

This part of ISO 8378 specifies the dimensional, physical and magnetic characteristics of the cartridge so as to provide physical interchangeability between data processing systems.

NOTE Numeric values in the SI and/or Imperial measurement system in this part of ISO 8378 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 re-converted. The original design was made using Imperial units and further developments were made using SI units.
