This standard is equivalent to the international standard S0/1FC:33--1988 Marking of information processing system recorded flexible disks 1 Title and scope of application
This standard specifies the markings on each flexible disk (FLK) and the minimum information on the packaging box (box) of unrecorded flexible disks.
The information specified in the standard should be marked on the packaging box of flexible and unrecorded disks for users to identify. The exact type of the floppy disk should be provided on the soft drive. This information is also included in the hands of the driver and system. 2 Reference standards || tt || Some of the following standards are relevant to this standard through reference in this standard. When the original standard is issued, the versions of these standards are effective and will be revised by all standard departments. Therefore, the units using this standard should study the possibility of adopting the new version of the standard. Each unit should pay attention to collect the latest versions of relevant standards, GRH416.1 Information processing data exchange 131mm modified frequency modulation system recording bit density of 718 revolutions/radian, channel density 1.9 channels/mm for double-sided floppy disks Part 1: Dimensions, physical properties and magnetic properties G71384 Information processing data conversion 200mr modified frequency modulation system recording bit density of 1322 flux reversals/radian, channel density 1.9 channels/mm for double-sided floppy disks Part 1: Dimensions, physical properties and magnetic properties GB/T[5130.1 Information processing data exchange 00mm improved frequency modulation system recording bit density of 1591G channels/radian, channel density 1.9 channels/mm for each side of the soft disk Part 1: Dimensions, physical properties and magnetic properties GR/T 15131.1
