Americans spell "floppy disk" with a "K" because it is a shortened version of "diskette." There are, however, many other instances of "disk" in common American usage (spinal disk, solar disk, etc.). "Disc" with a "C" actually is the exception. Traditionally, it applies mostly to flat, circular A-V media like like LPs, Videodiscs and Compact Discs. "MiniDisc" follows this thinking. However, since it is a trademarked name, there's no excuse for a company's communications rep to misspell it. Sony's U.S. marketing and communications "professionals" have been clueless about MD since its launch. I'm not surprised they can't even spell it korrectly. It's as if a Chevrolet flack were to write about a Korvette, or someone from Kimberly-Clark were to promote "Cleanex." Sony should fire the whole lot for incompetence, if not attrocious grammar. P.S. - Dear Sony: I have a degree in journalism and have written hundreds of articles for local, regional and national publications. I can spell "MiniDisc" and, unlike your PR drones, understand the difference between a USB data connection and a USB audio feed. My resumé is available on request.
