Information processing -- Magnetic disk for data storage devices -- 158 000 flux transitions per track, 210 mm (8.3 in) outer diameter, 100 mm (3.9 in) inner diameter
This standard was last reviewed and confirmed in 2010. Therefore this version remains current.
Lays down the mechanical, physical and magnetic characteristics for a lubricated magnetic disk of 210 mm (8.3 in) outer diameter and 100 mm (3.9) inner diameter intended for data storage devices. Defines requirements for a disk to enable satisfactory performance at 158 368 flux transitions per track. Other densities may necessitate modified characteristics.
