摘要： An illumination device is formed from a light-transmissive light guide member, and a light source disposed on a side of the light guide member to emit light to the light guide member. The light guide member is formed to include an anisotropic grating preferably at a boundary between an anisotropic member having a refractive index anisotropy and a substantially non-anisotropic member laminated on the anisotropic member. The anisotropic grating may be formed as a one-dimensionally arranged grating for causing selective diffraction of, e.g., an ordinary ray. As a result, the illumination device is caused to function as a planar light source emitting linearly polarized light of a uniform luminance distribution suitably used in combination with a transmission-type or reflection-type liquid crystal device to form a small-sized and thin liquid crystal apparatus.

摘要： A minute light spot is irradiated on an information track on a recording surface of a recording medium from an optical head. When reproducing an information mark train recorded on the recording surface by the mark position recording method, light reflected by or transmitted through the recording medium is guided to a divided photosensor having a division line extending in a direction perpendicular to the track. A plurality of outputs from the divided photosensor is arithmetically processed to thereby detect the central position of the information mark.

摘要： An optical information recording/reproducing apparatus realizes a direct verifying operation with a simple structure. A light beam emitted from a light source is converged on a track provided on an optical recording medium which is adapted to be moved relatively to the light beam. A super-resolution optical filter is provided in an optical path between the light source and the recording medium. The optical filter functions to produce a first light spot and a second light spot to be irradiated on the track such that the light intensity of the second light spot is lower than that of the first light spot and a recording signal is recorded using the first light spot. The signal recorded on the recording medium using the first light spot is reproduced by use of the reflected light caused upon the irradiation of the second light spot on the recording medium.
