A hologram recording/reproducing apparatus includes a recording/reproducing optical system that guides at least one of an information beam and a reference beam to an optical recording medium; a spatial light modulator that is arranged in an optical path of the recording/reproducing optical system, and spatially modulates a beam guided via the recording/reproducing optical system to generate the information beam; a first misalignment detecting unit that detects a first misalignment between the recording/reproducing optical system and the spatial light modulator using a beam for detecting the first misalignment; and a first misalignment correcting unit that corrects the first misalignment based on the first misalignment detected by the first misalignment detecting unit.
A hologram recording/reproducing apparatus, comprising:
A spatial light modulator arranged in an optical path of a recording/reproducing optical system that guides at least one of an information beam and a reference beam to an optical recording medium, and spatially modulates a beam guided via the recording/reproducing optical system to generate the information beam, comprising,
A hologram recording/reproducing method of correcting a first misalignment between a recording/reproducing optical system and a spatial light modulator in a hologram recording/reproducing apparatus that includes the recording/reproducing optical system guiding at least one of an information beam and a reference beam to an optical recording medium, and the spatial light modulator arranged in an optical path of the recording/reproducing optical system and spatially modulates a beam guided via the recording/reproducing optical system to generate the information beam, comprising:
