Usage notes
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 .Verb
