WebFigure 2: Cutaway image of 10-platter HDD As complex as these devices are, there are many potential failure modes. Obviously, they are delicate and fragile devices, and external shock can cause failures. The fly height of the heads above the platter is lower than the size of most particles, and particles between the head The flying height or floating height or head gap is the distance between the disk read/write head on a hard disk drive and the platter. The first commercial hard-disk drive, the IBM 305 RAMAC, used forced air to maintain a 0.002 inch (51 μm) between the head and disk. The IBM 1301, introduced in 1961, was the first disk drive in which the head was attached to a "hydrodynamic air bearing slider," which generates its own cushion of pressurized air, allowing the slider and head to fly m…
