Recently, under a cooperative research effort, TEAC Corporation, Mitsubishi Electric Company, and Tokyo Denka Company have developed a super high density record/reproduce technique for information such as image and sound, and one application of this technique, a new sound system named PCM Laser Sound Disc has been completed. In the video disc technique whereby an extremely small spot of laser beam is projected into a revolving disc for recording, and using the same laser beam, the recording is read out with no contact with the disc. Many applications have been proposed such as for home video, information file and acquisition, etc. We have employed this laser disc technique together with pulse code modulation to create a super hifi sound reproducing system for the home.
