SIS SS 63 67 37-1983 信息处理.应用改进调频制记录技术在130毫米(5.25 in)可折叠盒式磁盘上进行数据交换.磁盘密度为7 958 ftprad,双面.第2部分:磁轨格式
Information processing - Data inter- change on 130 mm (5.25 in) flexible disk cartridges using modified frequency modulation recording at 7 958 ftprad on both sides - Part 2: Track format
This part of ISO 7487 specifies the quality of recorded signals, the track layout, and the track format to be used on such a flexible disk cartndge, which is intended for data interchange be-tween data processng systems.
NOTE — Numenc 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
