  • Digital sound recording on motion picture film
    Patent number: 5677752
    Abstract: A motion picture film capable of reproducing the sound field full of ambience in the reproducing system. The digital sound tracks 5L and 5R, on which digital audio data have been recorded, are recorded so that temporally same digital audio signals are recorded with a spatial shift by a preset distance along the film running direction.
    Type: Grant
    Filed: November 25, 1996
    Date of Patent: October 14, 1997
    Assignees: Sony Corporation, Sony Cinema Products Corporation
    Inventors: Shinji Miyamori, Masatoshi Ueno, Matayasu Kubo, Kenji Takanashi, Toshiaki Setogawa, Michael J. Kohut, Jeffrey E. Taylor

  • Optical disk player having reduced laser output during track changes
    Patent number: 4660189
    Abstract: This invention relates to an optical disk recording and reproducing apparatus for recording a predetermined signal on and/or reproducing the same from a writable disk which is rotated at a constant linear velocity by using a laser from a laser source. In this case, upon reproducing the above-described signal, if a signal recorded on the inner periphery of the disk is accessed, during the period from this addressing up to the time when the linear velocity at the inner periphery of the disk becomes constant, on the basis of a spindle lock signal, the beam power of the laser from the laser source and irradiating the disk is decreased to thereby prevent useless data from being rewritten on the disk.
