Abstract: A magnetic recording tape cleaner comprises an element with a tape wiping surface. Tapes are cleaned by passing them over the surface which scrapes unwanted recording material particles from the tape surface. As these particles accumulate primarily at the edges of the tape, the wiping surface is curved to apply more wiping pressure to the edges of the tape than the center thereof.
