| 摘要 |
A magneto-optic recording apparatus which has a magnetic field generator that applies a magnetic field with a constant direction to a magneto-optic recording information medium for overwriting information to improve accuracy of recording and reproducing information onto and from magneto-optic recording information medium and further has an auxiliary magnetic field generator that compensates a variation of intensity of a magnetic field generated by the magnetic field generator and applied to the magneto-optic recording information medium is disclosed as the first invention. Also, a magneto-optic recording apparatus which performs synchronous wave detection of the reflected light signals from the magneto-optic recording information medium and controls A.C. voltages applied to an exciting coil of the magnetic field generator in response to the detected result of the synchronous wave detection, thus optimizing amplitudes of the reproducing signals from the magneto-optic recording information medium is disclosed as the second invention. |
