  • Patent number: 5976688
    Abstract: In a magneto-optical recording medium, a first dielectric layer 12, a recording layer 13, an auxiliary recording layer 14, a second dielectric layer 15 and a reflective layer 16 are sequentially laminated on a transparent substrate 11. Recording layer 14 is formed of a rare-earth transition-metal amorphous alloy having a film thickness of about several hundreds angstroms. Auxiliary recording layer 14 is also formed of a rare-earth transition-metal amorphous alloy. However, the Curie temperature T.sub.C2 of auxiliary recording layer 14 is 10.degree. K or more higher than the Curie temperature T.sub.C1 of recording layer 13, and the film thickness of auxiliary recording layer is ultra-thin, such as, 70 .ANG. or less. Further, the squareness ratio of auxiliary recording layer 14 at the Curie temperature T.sub.C1 of recording layer 13 is 0.7 or higher.

  • Patent number: 5843570
    Abstract: In a magneto-optical recording medium, a protective layer 14, a first magnetic layer 11 formed of a light rare earth element-heavy rare earth element-transition metal alloy, a second magnetic layer 12 formed of a light rare earth element-heavy rare earth element-transition metal alloy, a third magnetic layer 13 formed of a light rare earth element-heavy rare earth element-transition metal alloy, another protective layer 15, and a reflection layer 16 are laminated in sequence on a transparent substrate 10. The first, second and third magnetic layers are sandwiched so as to form a recording film 17. The compositions of the first and third magnetic layers are so selected as to provide a large Kerr rotational angle in a short wavelength range (400 to 700 nm), which is high in the ratio of light rare earth element.

  • Patent number: 5815469
    Abstract: To directly overwrite data on a magnito-optical recording medium formed of two exchange-coupled magnetic layers of a memory layer with a high coercive force and a low Curie point and a reference layer with a low coercive force and a high Curie point, an initializing magnetic field (e.g. 1000 to 5000 Oe) is applied to the medium to arrange the magnetization direction of only the reference layer; a recording magnetic field (e.g. 100 to 400 Oe) is applied and simultaneously a recording laser beam modulated according to data is irradiated upon the medium to record the data as magnetization directions of the memory layer; the initializing magnetic field is applied again to the medium to arrange the magnetization direction of only the reference layer; and a reproducing magnetic field (e.g. 1000 Oe or less) is applied and simultaneously a reproducing laser beam is irradiated upon the medium to reproduce the data.

  • Patent number: 5325345
    Abstract: When data are thermo-magnetically recorded to a perpendicular magnetized film of a recording medium, it is possible to prevent unnecessary magnetic domains from being formed and unerasable magnetic domains from being produced. The medium 11 is rotated by a motor 12. When being passed through a recording field generated by a magnet 14, the medium 11 is irradiated with a recording beam generated by an optical head 13, so that data can be recorded to a perpendicular magnetized film of the medium 11 as bubble magnetic domains. Further, when the medium 11 passes through a correcting magnetic field generated by a magnet 15 disposed away from the position at which data are recorded, unnecessary and/or unerasable domains can be eliminated.
