摘要： In order to improve a characteristic of an optical element, an optical element (polarizing filter) including a substrate 1S having a wire-grid region 1A and a peripheral region 2A positioned on an outer periphery thereof is made to have the following configuration. A wire-grid in which a plurality of line-shaped wires P10 made of Al and extending in a y direction are arranged at spaces S in an x direction is provided in the wire-grid region 1A of the substrate 1S, and a pattern (repetitive pattern) in which a plurality of protruding portions P20 made of Al are arranged is provided in the peripheral region 2A. This pattern is, for example, a checkerboard pattern. According to the above-mentioned configuration, the plurality of wires P10 can be arranged so that their respective ends are spaced apart from an end of the substrate 1S, so that the wires P10 can be prevented from being deformed and nicked. Also, by the plurality of protruding portions P20 in the peripheral region 2A, it is possible to prevent water from entering the wire-grid region 1A.

摘要： Provided are a medium structure which allows track narrowing onto a three-dimensional pit selection type disc, and its corresponding optical disc device. Multiple data pit strings are formed between track guide grooves, and a phase-change recording film is formed only in the data pit strings. Thereby, a disc configuration is achieved. Reflectivity and a phase of each of a space portion and a mark portion are appropriately set. Thereby, normal resolution signal cancel is implemented to prevent deterioration in data crosstalk and a push-pull signal. An optical disc medium of the present invention is supported by an optical disc device having a configuration in which a signal is selected from a push-pull signal of a main beam and push-pull signals of sub-beams to read out wobble address information.

摘要： A super-resolution material is formed in only a data pit, in a low temperature state of the super-resolution material, reflectivity of each of a pit portion and a space portion and an optical phase difference therebetween are set to be sufficiently small, in a high temperature state, and at least the optical phase difference between the pit and the space is set to be larger than the aforementioned value in an absolute value. Accordingly, by conducting irradiation with an appropriate read power by which substantially only one data track width can be heated to a high temperature state, a good push-pull signal can be obtained even with a track pitch being less than a diffraction limit. At the same time, by an optical device having functions such as a switching means with a DPP type, an offset correcting means of the push-pull signal due to lens shift, a shaping means of the push-pull signal, a learning means of read power, and the like, there is provided an optical disk device that corresponds to the optical disk medium of the present invention and achieves an increase in capacity.
