    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 .
