摘要： A hologram recording apparatus, a hologram recording method and a hologram recording medium reduce noise components generated by a phase modulation type spatial light modulator, thus permitting improved integrity of data to be achieved. A light beam whose diffraction state has been controlled by a diffraction control element is condensed on a hologram recording medium. With this arrangement, a predetermined diffracted light component is removed from a diffracted light beam emergent from the diffraction control element when recording information, which is based on the diffraction state controlled by the diffraction control element, in a hologram recording medium. Thus, noise components when information is recorded can be reduced.

摘要： A holographic recording/reproducing apparatus includes a splitter unit for splitting a laser beam into a first laser beam for generating a signal beam and a second laser beam which serves as a reference beam, a spatial light modulator for spatially modulating the first laser beam in accordance with information to be recorded, the modulated first laser beam serving as the signal beam, and a first lens system for focusing the signal beam and the reference beam onto a holographic recording medium. In a recording process, the signal beam and the reference beam are guided through one and the other half-regions separated along the optical axis of the first lens system. In a reproduction process, only the reference beam is guided through one of the half-regions and a signal reproduction beam from the holographic recording medium is guided through a second lens system in the other half-region.

摘要： In a micro mirror apparatus pivoting on a hinge part as its axis, a movable part connected to a stationary part through the hinge part enhances exclusively the flexural rigidity of the hinge part without causing any significant change in the torsional rigidity of the hinge part and thus widens servo band. To this end, on at least a part of the hinge part 14, a protrusion 14b protruding in the direction of its thickness is formed. This greatly increases the flexural rigidity of the hinge part 14 and widens the servo band.

摘要： A holographic recording and reproducing apparatus is provided. The holographic recording and reproducing apparatus includes a signal-beam spatial light modulating unit that displays a signal beam pattern for a signal beam, a reference-beam spatial light modulating unit that displays a reference beam pattern for a reference beam, and a controller that controls the mode of the signal beam pattern and that of the reference beam pattern. The controller controls the modes of at least two signal beam patterns and the modes of at least two reference beam patterns. A first reference beam is made to interfere with a first signal beam based on first recording data to record the data as a first hologram in a predetermined area of the holographic recording medium. A second reference beam is made to interfere with a second signal beam based on second recording data to record the data as a second hologram such that the second hologram is superimposed on the first hologram.
