    摘要： A hologram is recorded by irradiating, with a reference light beam, a region corresponding to an intensity distribution of a signal light beam on an optical recording medium. For example, the reference light beam having the intensity distribution which substantially coincides with the intensity distribution of the signal light beam is generated, and only the region which substantially coincides with the region irradiated by the signal light beam (i.e., the signal light beam defocused region) is irradiated with the reference light beam. This enables only the necessary region to be exposed and the regions which need not be exposed not to be exposed. Accordingly, the hologram can be recorded without losing information of the signal light beam and thus high-density recording can be realized.

    摘要： An optical recording/reproducing apparatus having excellent resistance against vibration and noise is provided. In recording, coherent light is polarization-modulated with a spatial light modulator to generate signal light and reference light whose polarization directions are crossed at right angles with each other. The signal light permeates a polarizing beam splitter, and is incident to a quarter wavelength plate. The reference light passes through a passing hole, is diffused by a light diffuser and is incident to the quarter wavelength plate. The reference and signal light are converted into circularly polarized light which revolve in directions opposite to each other and condensed by a condenser lens, and then a predetermined area of an optical recording medium is irradiated with the reference and signal light. Thus, the reference and signal light are generated by modulating the incident light from the same light source and are coaxially incident to the polarizing beam splitter.

    摘要： A holographic recording and/or retrieval method and apparatus are provided. An optical recording medium is used which has a recording layer, formed on a surface of a transparent substrate, through which light having an incident angle of a predetermined value or more with respect to the surface is guided, and which changes a refractive index or absorption coefficient upon simultaneous irradiation of signal light of a predetermined wavelength and reference light, and can record holograms by holding the changed refractive index or absorption coefficient. During recording, a hologram is recorded by simultaneously irradiating the recording layer with signal light of predetermined wavelength and reference light. During retrieval, reading light of wavelength that does not change a refractive index or absorption coefficient of the recording layer is guided through the recording layer, and a hologram is retrieved by diffracted light produced when the reading light is guided through the recording layer.

    摘要： In the present invention, a photosensitive layer of an optical recording medium includes a photo-responsive high-molecular compound comprising a photo-responsive group (e.g., an azobenzene derivative) which is geometrically isomerized by light radiation, and a liquid crystal linear mesogen group (e.g., a biphenyl derivative), wherein the photo-responsive group and the linear mesogen group are respectively bonded as side chains. The invention provides an optical recording medium enabling large scale recording by making the photosensitive layer thick without impairing recording characteristics. The photo-responsive high-molecular compound preferably comprises an aromatic ring on a main chain. Further, the photo-responsive high-molecular compound preferably comprises a structural unit which is capable of forming a liquid-crystalline or crystalline polymer and a structural unit which is capable of forming an amorphous polymer.

    摘要： A holographic recording method and a holographic recording apparatus capable of selectively rewriting or erasing only desired data without degrading data other than the desired data are provided. Holograms are multiple recorded per file, and page data in one file is multiple recorded, while page data in one file and page data in another file are not multiple recorded. Therefore, only the desired file can be selectively rewritten or erased without degrading the other files.
