Hard Disk (HD)

Medium for permanent storage of data. Magnetic platters, electronics and mechanics make up a hard disk. The platters are fixed to a spindle. On each side of a platter there is a read/write head. Each platter is divided in to tracks, which again is divided into sectors. A characteristic with hard disks is that the platters and the mechanics are in an airtight enclosure, and that the read/write heads do not touch the platters as long as the platters are rotating.
