適用范圍：This part of ISO 7487 specifies the quality of recorded signals, the track layout, and a track format to be used on such a flexible disk cartridge, which is intended for data interchange between data processing systems.NOTE — Numeric values in the SI and/or Impenal 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 re-converted. The original design of this part of ISO 7487 was made using SI units.
