摘要： A magneto-optical reproducing apparatus for reproducing from a magnetic film medium having at least a displacement layer, a switching layer, and a memory layer. A magnetic wall displacement is generated in the displacement layer in any region where the temperature exceeds the Curie temperature of the switching layer to effectively enlarge any recorded magnetic domain. The reproduced signal from the magnetic film medium is equalized with regard to waveform in an equalizer circuit and then fed to a magnetic wall displacement detection circuit that produces a magnetic wall displacement signal by using a differential signal or a secondary differential signal of the reproduced signal so as to provide a low bit error rate despite any sudden DC level variation in the reproduced signal.

摘要： In a three-spot tracking control system for a multi-layer optical disc, stray light of the signal-reproducing main beam from a layer other than the layer being reproduced leaks into first and second photodetectors receiving the reflected beam of two auxiliary tracking controlling beams to render the tracking operation unstable. In order to overcome this drawback, a first photodetector detects one auxiliary reflected beam from one or the other of the information signal layers of a double-layer optical disc. The second photodetector detects the other reflected auxiliary beam from the information signal layer. A first upper envelope detector detects the upper envelope signal of the reflected auxiliary beam. A second upper envelope detector detects the upper envelope signal of the detection signal of the other reflected auxiliary beam. A first subtractor subtracts the detected output by the first upper envelope detector 6 from the detection signal of the first photodetector. A second subtractor subtracts the detected output by the second upper envelope detector from the detection signal of the second photodetector. A third subtractor performs subtraction between outputs of the first subtractor and the second subtractor.

摘要： An optical pickup apparatus of the present invention for reading out information signals recorded on an optical recording medium such as magneto-optical disc is adapted to split by means of a light splitting element a light beam emitted from a light source into two light beam travelling in different directions, which are linearly polarized in normally intersecting directions and to convert the phases of the vibrational components along normally intersecting two axes on a plane normally intersecting the traveling directions of the two light beams and to irradiate the recording medium with two light beams which are differently polarized so that two beam spots are partially superimposed with each other on the recording medium. The superimposed beam spot area which is a read out area is made smaller than one of the beam spots in size so that a high resolution read-out is performed.

摘要： To increase the track density, that is, to improve the recording density of the optical disk of ultra-high resolving power reproduction type, grooves 4 are formed in a transparent substrate 2; phase pits 1 are formed on groove bottom portions 5 and land portions 6 of the grooves; and further a material layer 3 is laminated. A polycarbonate substrate is used as the transparent substrate 2. The material layer 3 is formed of such a material that the state is partially changed due to heat of the reading light in the optical spot of the reading light but returned to the original state after the reading light has passed, and in addition the reflection factor of the material is changeable according to the state change. The material layer 3 is a ternary compound of Ge.sub.2 Sb.sub.2 Te.sub.3. The thermal conductivity of the transparent substrate 2 is smaller than that of the material layer 3. The temperature of the material layer 3 rises in the laser spot according to the light intensity distribution of the laser, so that the reflection factor changes partially to enable data read operation. The heat conduction suppression due to the presence of the stepped portions of the grooves 4 sharpens the temperature gradient, so that the range in which the reflection factor is increased due to the state change of the material layer 3 can be reduced, thus decreasing the track interval distance and thereby increasing the track density.

摘要： A high density magnetooptical recording and playback method is disclosed. The magnetooptical recording medium comprises a recording hold magnetic layer and a playback magnetic layer magnetically coupled with each other. Prior to the playback operation, the playback magnetic layer is initialized by an external magnetic field. A laser light is irradiated to locally heat the medium and cause transfer of magnetization in the recording hold magnetic layer to the playback magnetic layer. The signal is read out by the interaction of the laser light and the transferred magnetization.
