摘要： PROBLEM TO BE SOLVED: To decrease distortion in an optical system without decreasing the use efficiency of light or increasing the cost of an apparatus. SOLUTION: In the hologram recording and reproducing apparatus 30 with a phase conjugate light reproducing system, the pixel pitch of an optical spatial modulator 31 for optical spatial modulation of signal light 100 is controlled to be identical to that of an imaging element 35 where reproducing light 300 irradiates for imaging. The pixel pitches in the optical spatial modulator 31 and in the imaging element 35 are made identical, as well as a polarized beam splitter 36 which efficiently separates the optical path of the signal light 100 from that of the reproducing light 300 because the polarization direction of the signal light 100 is controlled to be different by 90 degrees from the polarization direction of the reproducing light 300, by polarizing the reference light in such a manner that the polarization direction of the reference light 200 used for recording differs by 90 degrees from the polarization direction of the reference light 200' for reading.

摘要： PROBLEM TO BE SOLVED: To realize compatible reproduction between a plurality of devices for a hologram recording medium multiply recorded by a phase correlation multiplexed system. SOLUTION: A diffuser 23 is disposed at a part of a casing 21 of the hologram recording medium 20 using a cartridge, reference light 200 is made incident in the interior of the casing in a speckle shape through the diffuser 23 and interferes with signal light 100 whose intensity is modulated by data and interference fringes generated at this time are recorded in a recording medium 22. When the hologram recording medium using the cartridge is reproduced by an another reproducing device, the reference light (illumination reference light) 200 exhibits the speckle shape through the diffuser 23 and the reference light having the same speckle pattern as the recording speckle pattern can be formed with good reproducibility. Thereby, compatible reproduction of the hologram recording medium between the plurality of reproducing devices can be easily realized. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an optical information recording medium that can increase recording speed. SOLUTION: The optical information recording medium includes a recording layer 121 that has a recording area 121a on which a cavity is formed as a recording mark RM as a result of an increase in temperature around a focal point after absorbing a recording beam L2c converged for recording of information in accordance with the wavelength of the recording beam L2c and from which, when a predetermined reading beam L2d is emitted for reproducing of the information, the information is reproduced based on a returned beam L3. Further, the recording layer 121 has a non-recording area 121b provided adjacent to the recording area 121a to suppress dispersion of the heat around the focal point when the recording beam L2c is radiated.

摘要： PROBLEM TO BE SOLVED: To provide an optical information recording medium capable of improving reproduction characteristics. SOLUTION: The optical information recording medium formed by curing liquid resin M1 forms a recording mark RM by absorbing a recording light beam L2c which is predetermined recording light collected when recording information and raising temperature near a focus Fb, and reproduces information based on a return light beam L3 which is return light corresponding to the irradiation of a read light beam L2d which is predetermined read light when reproducing the information. A curing degree differs according to irradiation energy by lowering the curing degree near a substrate 102 with large irradiation energy of the recording light beam L2d assumed to irradiate a target position where the recording mark RM is recorded, and the curing degree is raised near a substrate 103 with small irradiation energy.

摘要： PROBLEM TO BE SOLVED: To locally cure a hologram recording medium without using a tool, such as a mask, by easily and surely curing the hologram recording medium by using signal light.
SOLUTION: Random patterns changing at a high speed are displayed in a spatial optical modulator 1 by a spatial optical modulator driving device 6, and thereby, the signal light 100 randomly intensity modulated by the random patterns changing at the high speed are generated. The hologram recording medium 3 is cured by using the signal light 100. Since the wave front of the signal light 100 changes at the high speed, the spuriously incoherent light is formed and therefore the hologram recording medium 3 can be easily and surely cured without deterioration of a recorded image. In addition, the hologram recording medium 3 is locally and simply cured by using a servo of an existing signal light optical system.

摘要： PROBLEM TO BE SOLVED: To prevent deterioration of the S/N ratio of reproduced image data due to incidence of unnecessary light on an optical system of reproduced light during reproduction without affecting the recording multiplexing degree of an angle multiplexing system, and to upgrade the quality of a reproduced image.
SOLUTION: Deterioration of the S/N ratio of reproduced image data due to incidence of unnecessary light on the optical system 15 of reproduced light during reproduction is prevented without affecting the data multiplexing degree of the angle multiplexing system by setting a hologram recording medium 12 in such a way that the axis 60 of rotation of the hologram recording medium 12 makes a prescribed angle other than a right angle with respect to the optical axis 50 of an optical system 11 of signal light when the hologram recording medium 12 is set to be inclined with respect to the lens 121 of the optical system of signal light, whereby the quality of a reproduced image can be upgraded.

摘要： PROBLEM TO BE SOLVED: To provide a hologram recording and reproducing device and method capable of making the degree of multiplexing of holograms by an angle multiplexing system higher than heretofore without degrading crosstalk within a limited movable range of a reflection mirror to change the incident angle of reference light and capable of making the movable range of the reflection mirror narrower than heretofore when the degree of multiplexing of the hologram is not raised.
SOLUTION: At the time of multiplex recording the holograms to the same region by changing an incident angle of reference light on the hologram recording medium in recording the interference fringes of the reference light and signal light to the hologram recording medium, the angle pitches of the incident angle of the reference light are changed like Δθ
1 , Δθ
