ABSTRACT:
A recording reproducer is disclosed for use with a magnetic card comprising a non-magnetic material such as paper having a coating of a powder of magnetizable material on its back surface. The recording reproducer includes a transducer element such as a magnetic head which translates a magnetic energy into electrical energy or vice versa. In the region of the coating of magnetizable material, a sound track is formed on the card for recording a sound. By moving the magnetic head from a start position toward a terminal position of the sound track while maintaining contact between the head and the track, the sound is reproduced. The magnetic head may be returned instantaneously from the terminal position, or an arbitrary intermediate position between the terminal position, and the start position to the start position, whereby the sound can be repeatedly reproduced by repeating the playback and returning motion.
