Title: Magneto-optical recording medium
Inventor: KIKITSU SATORU
IPC: G11B11/105
Filed: 1991-09-30
Abstract: PURPOSE:To improve a recording density by providing a recording layer recorded with magneto-optical information and a reproducing layer for reproducing the magneto- optical information of the recording layer and forming this reproducing layer of any one kind among 4 kinds of materials. CONSTITUTION:Inversion magnetic domains are formed in the recording layer 1 when the recording layer is pulsively irradiated with a laser beam of a recording level while a magnetic field is kept impressed thereto with a magnetic fixed from the outside. The reproducing layer 2 is formed of the material which makes phase transition from antiferromagnetism to ferromagnetism with an increase in temp., the spin rearrangement material, the magnetic anistoropy of which changes from an intra-surface direction to a perpendicular direction with respect to the substrate surface, the material which makes phase transition from ferromagnetism to antiferromagnetism with an increase in temp., and the spin rearrangement material, the magnetic anistropy of which changes from a perpendicular direction to an intra- surface direction with respect to the substrate surface. The inversion magnetic domains of the reproducing layer are made smaller than the inversion magnetic domains of the recording layer in such a case and can be made smaller than a laser spot. The recording density is thus increased.

Abstract: PURPOSE:To obtain a semiconductor laser having optical switching characteristics, a current narrowing high efficiency by combining multilayer films composed of predetermined thickness of quantum wells, setting the thickness of a semiconductor contact layer of an output side to a special value, and specifying compound of the semiconductor layer. CONSTITUTION:When a current flows forward between electrodes 111 and 101 and a light of a wavelength corresponding to a quantum level difference of a quantum well layer 107 is irradiated, lights having different wavelengths are output from quantum levels n=1 and n=2. In this case, a resonator is formed between upper and lower multilayer film mirrors, and a laser oscillation from the quantum level n=2 of high reflectivity occurs. When a light of a wavelength corresponding to n=1 is externally input in this state, the level of the laser oscillation is shifted from n=2 to n=1, and optical switching can be externally performed. Further, since leakage of injected current to the high resistance buried layer does not occur, current narrowing is performed. Further, an effective light confinement is performed by a rib waveguide structure using a ZnS0.06Se0.94 layer.
