In International English, disk is the correct spelling for magnetic disks. If the medium is optical, the variant disc is usually preferred, although computing is a peculiar field for the term. For instance hard disk and other disk drives are always thus spelled, yet so are terms like compact discs. Thus, if referring to a physical drive or older media (3" or 5.25" diskettes) the k is used, but c is used for newer (optical based) media.
Less commonly, in British English, disc has been used for magnetic disks, as in floppy disc and discette.
