Hard disk drive is the mechanism that reads and writes data on a hard disk. Hard disk drive has many inflexible platters (discs) coated with magnetic material. Read/write heads can record computer data on these discs. A typical hard disk rotates at 3,600 revolutions per minute, and the read/write heads ride over the surface of the disk on a cushion of air 25 micron deep. Hard disk drives (HDDs) for PCs generally have seek times of about 12 milliseconds or less. Hard disk drives are sometimes called Winchester drives. Winchester is the name of one of the first popular hard disk drive technologies developed by IBM in 1973.
