Usage notes

In most varieties of English, disk is the correct spelling for magnetic media (hence hard disk or disk drive), whereas the variant disc is usually preferred with optical media (hence compact disc or disc film). 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. For all other uses, disc is standard in Commonwealth English and disk in American English.

Less commonly, in British English, disc has been used for magnetic disks, as in floppy disc and discette. Such usage may be considered nonstandard.
