Abstract: A sound-recording technique has been devised that uses light-emitting diodes and fiber-optics to expose the soundtracks; then optical fibers couple the soundtracks to phototransistors for playback. The soundtracks produced by this method are variable density. Test results and limitations are presented. The capability of recording a photographic film soundtrack in 1/100-in (0.254-mm) width and 16 parallel tracks in less than 5 mm (0.197 in) may have application to wide-screen motion picture soundtracks in the future.
