'''Disk storage''' (also sometimes called '''drive storage''') is a [[data storage]] mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A '''disk drive''' is a device implementing such a storage mechanism. Notable types are [[hard disk drive|hard disk drives]] (HDD), containing one or more non-removable rigid [[hard disk drive platter|platters]]; the [[floppy disk| floppy disk drive]] (FDD) and its removable [[floppy disk]]; and various [[optical disc drive]]s (ODD) and associated [[optical disc]] media.

(The [[Spelling of disc|spelling ''disk'' and ''disc'']] are used interchangeably except where trademarks preclude one usage, e.g., the Compact Disc logo. The choice of a particular form is frequently historical, as in IBM's usage of the ''disk'' form beginning in 1956 with the "[[IBM magnetic disk drives#IBM 350|IBM 350 disk storage unit]]".)
