摘要： In a combined optical and magneto-optical recorder, data stored in pits and a magnetic layer may be simultaneously detected with an optical scanning device. Reflected light is divided by a polarizer and directed to one of two photodetectors depending on the polarization of the reflected light. A magneto-optic recorded data signal (containing cross-talk) is detected by differencing the signals provided by the two photodetectors. Reflected light is also directed through a .lambda./4 polarizer and a second beam divider to third and fourth photodetectors depending upon the polarization of the light passing the .lambda./4 polarizer. A second difference signal, which essentially conforms to the cross-talk, is generated from the differences of signals provided by the third and fourth photodetectors. The two difference signals are combined to produce a cross-talk free magneto-optic recorded data signal.

摘要： An optical pick-up for scanning a magneto-optically recorded disk in which the disk reflects a first principal beam onto a first photodetector. This first principal beam has a plane of polarization which is rotated in one direction. The recorded disk reflects a second principal beam onto a second photodetector. This second principal beam has a plane of polarization that is rotated in another direction. A data signal is generated from the difference between output photovoltages of the first and second photodetectors. A diffraction grating splits the main beam from a light emitting source, into the principal beams and into subsidiary beams. The main beam from the light emitting source is focused on the recorded disk through the diffraction grating. Auxiliary photovoltages are generated from the auxiliary beams, and these are subtracted for generating the data signal. The output voltage of the second photodetector has noise components that are in phase and which are generated by the main beam. This output voltage of the second photodetector contains also noise components of opposite phase that are generated by the subsidiary beams. The output signal of the first photodetector, on the other hand, has only noise components generated by the main beam.

摘要： An optical information recording/reproducing apparatus includes an optical pickup unit that acquires access-restriction codes (number of reproductions, number of copies, effective period, and end date) under control of a controller. The controller determines whether it is permitted to reproduce information recorded on the RAM data-layer based on acquired access access-restriction codes (number of reproductions, number of copies, effective period, and end date). When the reproduction is permitted, the controller sends the information recorded on the RAM data-layer to a host computer.
