    摘要： While Fourier transformation of a signal light beam is performed to perform recording during holographic recording so that a focal point is formed outside a holographic recording layer (defocus recording), an aperture is arranged on an outgoing side of the reproduced signal light beam (reproduction light beam), the reproduction light beam is focused at the aperture, and low-order components of a Fourier transform image of the reproduction light beam are selectively transmitted to detect only the transmitted light beam. Therefore, information recorded as the hologram in the holographic recording layer can be reproduced with high S/N ratio from the holographic recording layer added onto a support body, particularly onto a sheet member having non-optical quality such as paper and a plastic card.

    摘要： A shredder that shreds a recording medium which includes, on a surface thereof, an image forming portion and a holographic memory portion in which data is recorded. The shredder includes a data destroying unit that destroys at least the data recorded in the holographic memory portion and a shredding unit that shreds the entire recording medium. Thus, when a recording medium to which has been added a holographic memory portion in which useful information is recorded is to be discarded, the data(information) recorded in the holographic memory portion can be safely destroyed so that the data can no longer be read.

    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： The present invention relates to a method for producing an optical recording medium. In the method, on the surface of a recording layer formed by spin-coating a first coating solution containing a photo-isomerizable component, a second coating solution that contains a photo-isomerizable component that can be isomerized by radiation having the same wavelength as radiation used for isomerizing the photo-isomerizable component contained in the recording layer and incapable of dissolving the recording layer is spin-coated to form an intermediate layer. Since the intermediate layer thus formed cannot be dissolved by the first coating solution, a recording layer is further laminated on this layer. Thus, it becomes possible to make the recording layer thicker and also to provide a high-density recording characteristic.

    摘要： Laser light output from a laser light source is irradiated onto a transmission-type scale. Due to movement of the transmission-type scale, a polarization angle of transmitted light varies in accordance with variations in orientations of half-wave plates arrayed in a longitudinal direction. It is difficult for the polarization angle to be affected by noise factors such as external light or the like. Light intensity of a polarized light component, which is transmitted through an analyzer and detected at a photo-detector, varies in accordance with the polarization angle. Thus, the light intensity varies as the transmission-type scale moves, and a detection signal is output to a movement amount computing device. When an amount of movement is computed on the basis of the signal, the exact amount of movement can be detected.
