  • Magneto-optic recording system
    Patent number: 5528565
    Abstract: A magneto-optic recording system uses a unit recording medium having on a substrate a first magnetic layer whose Curie temperature is low and also having on the first magnetic layer a second magnetic layer whose Curie temperature is high. The system heats a spot on the medium with a heating device. The system may employ two such unit recording media, each having the second magnetic layer magnetized in one direction. The two unit recording media are superposed on each other and formed integrally so as to obtain a magneto-optic recording medium in which the amount of information recorded and the recording speed are doubled. In addition, a light-emitting device and a magnetic field generator are added to the magneto-optic recording medium to obtain a compact magneto-optic recording system with a low level of power consumption.
    Type: Grant
    Filed: February 23, 1995
    Date of Patent: June 18, 1996
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Isao Watanabe, Koichi Takeuchi, Osamu Ito, Kyosuke Yosimoto, Kunimaro Tanaka, Kazuhiko Tsutsumi
  • Magneto-optic recording medium method of manufacturing the same and magneto-optic recording system
    Patent number: 5481508
    Abstract: A unit recording medium, having on a substrate a first magnetic layer whose Curie temperature is low and also having on the first magnetic layer a second magnetic layer whose Curie temperature is high, is heated by a heating device. After two such unit recording media each having the second magnetic layer magnetized in one direction are fabricated, and the fabricated two unit recording media are superposed on each other and formed integrally so as to obtain a magneto-optic recording recording medium in which the amount of information recorded and the recording speed are doubled. In addition, a light-emitting device and a magnetic field generator are added to the magneto-optic recording medium to obtain a compact magneto-optic recording system with a low level of power consumption.
