标准范围

描述了以7958 ftprad、1.9 tpmm(48 tpi)的速度记录的130 mm(5.25 in)盒式软磁盘的特性,使用改进的调频记录在两侧。定义所记录信号的质量、磁道布局(磁道格式A),用于数据处理系统之间的数据交换。如果符合第1部分和第2部分或第2部分和第3部分的所有要求,则与ISO 7487一起适用。

Describes the characteristics of 130 mm (5.25 in) flexible disk cartridges recorded at 7 958 ftprad, 1,9 tpmm (48 tpi), on both sides using modified frequency modulation recording. Defines the quality of the recorded signals, the track layout (track format A) to be used on such a flexible disk cartridge intended for data exchange between data processing systems. Applicable in conjunction with ISO 7487 if it meets all requirements of part 1 and 2 or those of parts 2 and 3.
