disk drive

A storage device that holds, spins, reads and writes magnetic disks or optical discs (CD, DVD, MO, UDO). In this encyclopedia, disk ("k") refers to a magnetic disk drive, and disc ("c") means an optical drive. Magnetic disk drives contain non-removable platters; however, optical drives are receptacles for removable discs or cartridges. See magnetic disk, CD, DVD, magneto-optic disk and UDO.
