An erase system for degaussing a magnetic tape in a cassette including a receptacle-forming housing defining a receptacle for insertion of the cassette in one orientation and preventing insertion in another orientation. The system also includes a degaussing means mounted for providing a quick and simple degaussing operation whereby the magnetic tape is twice exposed to the field produced by the degaussing means. A mechanism is provided to insure a quick return of the cassette to the operator with the degaussing means being energized by a switch operable by the action of the return mechanism.
