摘要： Quality of a reproduced light beam is improved, and rewriting and recording are performed at high speed without erasing data. Each page of a hologram is newly recorded so that the maximum point of diffraction light beam intensity in reproducing the newly recorded hologram is located at a position where diffraction light beam intensity from a data page of a hologram which has been previously recorded in a hologram recording medium is minimized at the time of reproducing the data.

摘要： The present invention relates to a method of producing digital holograms in a storage medium, in which the technical problem of writing computer-generated holograms by means of optical lithography as quickly as possible and with little effort with simultaneous accurate control of the timed triggering and the positioning of the write beam is achieved in that a write beam is focused onto the storage medium and moved one-dimensionally relative to the storage medium, in that a scanning beam is focused onto a trigger mask having a plurality of trigger lines and moved one-dimensionally transversely relative to the trigger lines, the movement of the scanning beam being coupled with the movement of the write beam, in that, during the scanning of the trigger lines, a timed trigger signal is generated as a function of the arrangement of the trigger lines, in that, with the aid of the timed trigger signal, the intensity of the write beam on the storage medium is controlled, and in that the hologram is written line by line by introducing radiation energy point by point, the storage medium being displaced transversely with respect to the scanning direction of the lines by a predefined distance to write adjacent lines of the hologram. The technical problem is also solved by a lithograph for producing digital holograms.

摘要： There are provided a recording material for holograms characterized by low corruption of recorded data with time, a manufacturing method thereof, a recording medium for holograms, a hologram recording method and a hologram reproduction method. The recording material for holograms of this invention comprises a metal oxide porous body provided with an oxygen donor substance in the pores. In the recording material for holograms, recording is accomplished by increasing the oxygen content of the metal oxide porous body with oxygen from the oxygen donor substance produced upon irradiation of recording light. The irradiated sites undergo no further alteration even with additional light irradiation, and the heat-induced volume fluctuations are negligible. The recording material for holograms exhibits reduced corruption of recorded data with time when subjected to repeated reproduction or when the recorded medium is stored for long periods.

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： In a holographic digital data storage system, holographic page data has at least two concentric patterns with the optical information arranged within an outermost pattern of at least two concentric patterns. Since at least two concentric patterns in the holographic page data are deformed into at least two elliptic patterns in the diffracted beam caused by irradiation of the reference beam, at least two elliptic patterns are extracted from the diffracted beam and then at least two elliptic patterns are estimated to generate at least two estimated concentric patterns. A compensated vector between said at least two elliptic patterns and said at least two estimated concentric patterns is used to reconstruct the optical information from the diffracted beam.
