ABSTRACT:
A cassette having improved erasing means is disclosed. The cassette has a top and a base which define a front wall. The front wall defines an opening through which the tape passes on its way to a take-up reel mounted in the base. A magnet which is aligned in a horizontal orientation is mounted adjacent the opening. As the tape passes the magnet, the signals on the tape are erased. The magnet is moved out of its erase position to allow redubbing of the tape.
