We have developed the MUSE videodisc with a playback time of 60 minutes per side by doubling the disc recording density and using the optical pick-up with a 670nm LD. Two kinds of PCM stereo sound (time-division and frequency-division multiplexing) is recorded. High quality playback image with 43.5 dB S/N free from crosstalk is obtained by the disc with the linear velocity of 14 m/s and the track pitch of 1.12 μm.
