摘要： An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical-deflection element.

The optical path deflecting element includes a pair of transparent substrates, transparent electrode films on the substrates to which a voltage having an inverse polarity is selectively applied, an alignment layer in the inner sides of the substrates, and a liquid crystal layer formed of a chiral smectic C phase between the substrates via the alignment layer and homogeneously aligned by the alignment layer. The optical deflecting element can realize the uniformly-aligned liquid crystal layer more easily than a case in which the liquid crystal is aligned to become in a bistable condition. For this reason, it is possible to improve yield in the fabrication.

摘要： A magneto-optical recording method for recording information in an overwrite mode in a magneto-optical recording medium by the application of a laser beam is disclosed. The magneto-optical recording medium includes a substrate, and at least two magnetic recording layers overlaid thereon, with an exchange force working at least between the two magnetic recording layers, and the Curie temperature of each of the two magnetic recording layers being substantially the same. The magneto-optical recording method includes the step of conducting overwriting information by changing the power of the laser beam to be applied to at least two different levels, one at which the magnetic recording layers are heated to a temperature near or higher than the Curie temperature, and the other at which the magnetic recording layers are heated to a temperature lower than the Curie temperature, while a magnetic field is applied to the magneto-optical recording medium in one direction, in accordance with signals to be recorded in the magneto-optical recording medium, and this recording method requires only one initialization by the application of the magnetic field, but does not require any further initialization thereafter.
