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 thusly 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 is used for newer (optical based) media.
