disk drive
disk drive (disk unit) A device with
read/write heads and associated electronics that can store and retrieve data from one or more rapidly rotating
magnetic disks. The disks may be
hard disks or
floppy disks. The term can also be applied to devices operating with
optical disks.
In a magnetic disk drive the data is recorded on one or both sides of a disk in a set of concentric tracks, which are usually subdivided into
sectors. The read/write heads of the disk drive are mounted on arms that can be moved, by means of an
actuator, to position the heads accurately over the required track. As the disk rotates, the sectors on that track are made accessible. Storage locations can be accessed directly and in any order; typical
seek times are in the range 8–20 milliseconds while the
latency may be 8 milliseconds. The data is encoded according to a particular
disk format. See also
access time,
fixed disk drive,
floppy-disk drive,
disk array,
RAID.
