摘要： During reconstruction, the hologram cannot be reconstructed at high speed. In the present invention, the distance between the optical system base point, which is associated with a recording medium address during recording, and the recording medium is measured, and said distance is recorded in a memory. During reconstruction, distance information, which is the distance of the recording medium from the memory that is associated with a recording medium reconstruction address, is read, and the position of an aperture filter is adjusted at high speed in the optical axis direction on the basis of the read distance information and a distance measurement result for the optical system base point during reconstruction and the recording medium. Thus, the relative positions of the hologram within the recorded medium associated with the optical system during reconstruction and during recording can be matched.

摘要： An optical information recording/reproducing apparatus for recording information on a recording medium and/or reproducing information from the recording medium, includes: a laser light source for performing recording and/or reproducing information; a shielding part, using a liquid crystal, that can switch between transmission and interception of laser light emitted from the laser light source; a driving circuit for driving the switching between transmission and interception of the shielding part; a moving part for relatively moving the shielding part and the laser light; and a controlling circuit for controlling the moving part. The moving part relatively moves the shielding part and the laser light so as to switch a region to which the laser light is applied from a first region of the shielding part to a second region thereof different from the first region, in order to prevent the liquid crystal from deteriorating.
