Disc vs. Disk: What’s the Difference?

For the next couple hundred years, the only thing that might determine with any consistency whether you wrote disc or disk was where you lived: Americans favored disk, while disc was the spelling of choice in the UK. It’s still a toss-up between disc and disk for many kinds of discs (or disks). The music industry has used disc more frequently than disk ever since disc-shaped records became popular in the late 19th century, and modern music-related phrases like compact disc and disc jockey generally stick to that rule.
