Scope
GB/T15133 stipulates the performance of a 200mm single-sided floppy disk with a bit density of 13262 magnetic flux reversals/radians and a track density of 1.9 tracks/mm recorded in a dual-frequency system. GB/T15133.2 specifies the quality, track configuration and track format of the recorded signal. The labeling system specified in GB/T15133.1, GB/T15133.2 and GB/T15134 provides conditions for all data exchange between data processing systems. This standard specifies the dimensions, physical properties and magnetic properties of the above-mentioned floppy disks to ensure practical interchangeability between data processing systems. This standard is equivalent to ISO5654/1-1984 "Information Processing - Single-sided floppy disk with a bit density of 13262 magnetic flux reversals/radian and a track density of 1.9 tracks/mm for 200mm dual-frequency recording for data exchange. Part 1: Dimensions and physical properties and Magnetic Properties”.
