Paper Abstract

A high-definition videodisc with 60 minutes of playback time per side has been developed by doubling the disc recording density and using an optical pick-up employing laser diode with a wavelength of 670 nm. MUSE (Multiple Sub-Nyquist Sampling Encoding) video signal and two kinds of PCM sounds are recorded. In the disc with a linear velocity of 14 m/s and a track pitch of 1.12 micrometers , a playback image without cross-talk noise was obtained. In this paper, the development of a disc recording and playback system, and the optimization of recording conditions, which were carried out to achieve 60 minutes of playback time per side, are described.
