Abstract
According to one embodiment, an optical information recording apparatus includes a spatial light modulator, an optical mechanism, a driving module, and a controller. The spatial light modulator converts an irradiation beam emitted from a light source to plural partial information beams that carry information by causing the irradiation beam to pass through plural modulation areas. The optical mechanism collects the partial information beams onto an optical information recording medium and applies a reference beam onto the recording medium such that the reference beam and the partial information beams intersect with each other on an information recording layer. The driving module drives the recording medium or the optical mechanism. The controller performs angle multiplex recording of information on the information recording layer by controlling the driving module and causing the light source to emit the irradiation beam while switchingly supplying the modulation areas with the information.
