摘要： Binary two-dimensional digital data can be recorded in an optical recording medium as holograms in such a way that a recording area is made sufficiently minute correspondingly to the two-dimensional digital data by adequately limiting the spread of signal light and reference light without causing loss of the data and a read error during reconstructing. Signal light of a binary two-dimensional digital data image is subjected to Fourier transform by a lens. There is disposed forwardly of an optical recording medium a shading material having a circular, semicircular, sectorial, or L-shape light transmission part 21 that allows transmission of only components of 0th to n-th (n=1, 2, or 3) orders. The signal light after Fourier transform and reference light are transmitted through the light transmission part 21 for irradiation to the optical recording medium and a Fourier transform hologram is recorded in the optical recording medium.

摘要： A method and an apparatus capable of filtering based on desired spatial frequency characteristics without loss of Fourier spectrum frequency components, and of matched filtering of high recognition capability without losing functions of data recording and reconstruction as well as high-speed transmission and retrieval features and mass storage capacity characteristic of a holographic memory. Fourier transformed object light with 0° polarization of a target image is stored as a hologram using reference light having a spatial polarization distribution such that a daughter wavelet on scale m has 90° polarization. The hologram is retrieved using the Fourier transformed object light with 0° polarization. The hologram yields diffracted light in the form of a spatial frequency component which corresponds to scale m and is polarized 90° with respect to the other spatial frequency components. A polarizing element is used to extract only the spatial frequency component corresponding to scale m. Given reference light having a spatial polarization distribution in conformity with a shape of a spatial frequency filter, retrieval light of 0° polarization is applied for low-pass and high-pass filtering upon reconstruction.

摘要： An optical recording medium, an optical recording and reproducing method, and an apparatus that can record and reproduce multilevel information at a high density and with a high S/N ratio. Recording light emitted from a light source is collimated by a collimation lens and introduced into a polarization rotary device. Recording light transmitted by the polarization rotary device is focused by an objective lens onto an optical recording medium. In response, a photo-induced birefringence is recorded on the optical recording medium. Multilevel recording is performed by controlling a voltage applied to the polarization rotary device to change a polarization angle θ of recording light. Reproduction is performed by detecting light reflected from the optical recording medium with an analyzer and a detector.

摘要： An optical head which implements high recording density of a recording medium and which is miniaturized in size and improved in data transfer rate, a disk apparatus, and a method for manufacturing the optical head are provided. A laser beam is emitted from a semiconductor laser, the laser beam is collimated by the collimator lens to a collimated beam and reflected by a mirror, condensed by an condense lens, and incident to an incident surface of a transparent condensing medium. The condensed beam which was incident to the incident surface is refracted by the incident surface, the refracted beam is condensed on a condense surface, a beam spot is formed on the condense surface, and a near field wave leaks from a small aperture. The near field wave leaked from the small aperture propagates in a recording layer of a recording. The beam is served for recording/reproduction on the recording layer.
