    Abstract: A holographic recording medium in which information can be reproduced by phase conjugate beam without requiring a mirror for obtaining the phase conjugate beam and its driving part and recording density is not reduced. The recording medium includes a recording layer in which an interference pattern is recorded and a light absorption/transmission layer which can be reversibly changed to be in a first state where signal beam and reference beam passed through the recording layer are absorbed at the time of recording of information and a second state where the reference beam is transmitted at the time of reproduction of information, and the reference beam transmitted through the light absorption/transmission layer is reflected by a reflection layer to produce the phase conjugate beam.

  • Patent number: 8520484
    Abstract: In an optical information reproduction method for reproducing information using holography from a medium which records an interference pattern generated when overlapping a signal beam and a reference beam, the reference beam is radiated to the medium at a reference beam angle with a predetermined range for reproducing the information, a reproduction beam is generated by diffracting the reference beam with the interference pattern, the reproduction beam is detected by a photodetector; and the information is reproduced by processing a signal detected by the photodetector.

  • Patent number: 8427582
    Abstract: A video processor and method for swiftly detecting swaps occurring between links during transmission of images by the dual-link system. A first image combiner unit combines an image D1 of a first link as an odd-numbered image, with an image of a second link, to generate a first combination image. A second image combiner unit combines an image of a second link as an odd-numbered image, with the image of the first link to generate a second combination image. An edge detector unit detects the horizontal edge of the first combination image and the second combination image. A judgment unit compares the number of triple edges in the first combination image and second combination image, and judges the combination image having more triple edges as the error image. The triple edges contain three consecutive edges along the horizontal direction, and the rising edges and falling edges are arrayed alternately.

  • Patent number: 8305862
    Abstract: The optical information recording and reproducing device utilizing holography requires the optical system to generate the signal beam and the reference beam to be irradiated to the holographic storage medium as well as another optical system to generate the curing light beam to be irradiated to the holographic storage medium. Furthermore, from the viewpoint of backward compatibility, if the same device is used for recording or reproduction on the conventional optical discs represented by Blu-ray Disc, another optical system adaptable to recording and reproduction on these optical disks is required. This means the optical system configurations become complicated and larger in size. One solution for downsizing is to use the reference beam also as the curing light beam. Another way is sharing of optical path for curing light beam and for the reference beam. Furthermore, it is possible to share the light source for generating the curing light beam and for generating the recording or reproducing light beam.
