Ask Mr. Modem!
Q. Sometimes I see the word disk spelled disc, and other times as disk. I know I'm probably nitpicking, but which is correct?
A. If you're into picking nits, you've come to the right place! When new words enter the English language, they often appear in one or more variations until one form prevails over the others. There are also occasions when competing forms remain in use for a long time. Such is the case with disk and disc.
