    摘要： The present invention discloses a hologram erasing method, in which a predetermined hologram is erased by irradiating a predetermined region of a hologram recording medium in which the hologram to be erased is recorded with a reference light beam and a signal light beam holding a random data pattern at the same time. In this method, the signal light beam and the reference light beam interfere with each other in the medium, and a Fourier transform hologram recorded in the region where the interference occurs is destroyed and erased by interference light beam. That is, a data page for erasing including a random pattern is overwritten to erase an original data page. According to the present invention, the hologram recorded in the optical recording medium can be selectively and completely erased in a simple method.

    摘要： There is provided a data playback method including: acquiring first image data by illuminating reference light for reading onto an optical recording medium on which a hologram has been recorded by Fourier transforming and simultaneously illuminating reference light and signal light expressing digital data as a light-and-dark image, and detecting an inverse Fourier-transform image of diffracted light which is diffracted by the recorded hologram; acquiring second image data, which is a reversal image of the first image data, by generating combined light by combining the diffracted light and a dc component whose phase is different than a phase of a dc component of the signal light included in the diffracted light, and detecting an inverse Fourier-transform image of the combined light; and computing a difference in luminance for each pixel of the light-and-dark image, by carrying out computing processing by using the first and second image data.

    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： 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.
