The optical information recording device includes a light source configured to emit a laser beam, an optical element configured to divide the laser beam into the reference beam and the signal beam, an angle control unit configured to control an angle of incidence of the reference beam on the optical information recording medium, and a phase control unit configured to control a phase of at least one of the signal beam and the reference beam in a recording period, wherein the angle control unit controls an angle interval so that a position of a 1st null of an adjacent page of the signal beam is fixed, and wherein the phase control unit controls the phase of the signal beam or the reference beam so that a phase difference between the adjacent pages is a predetermined value.
An optical information recording device which multiplex-records a hologram corresponding to an angle of incidence of a reference beam as a page on an optical information recording medium at the time of recording an interference pattern of a signal beam and the reference beam as the hologram on the optical information recording medium, comprising:
