<P>PROBLEM TO BE SOLVED: To more highly efficiently record or reproduce information by using polarization holographic recording. <P>SOLUTION: The optical information recording device has space modulation means and information recording means. The space modulation means is configured such that polarization for reference light and polarization for signal light are generated and the polarization azimuths of the polarization components of the polarization for the signal light having polarization azimuths different from each other are independently changed for each pixel by using at least plural spatial light modulators, thereby adding information to each of the polarization components. The information recording means superposes the signal light and the reference light generated by adding the information to the polarization components and emits the signal light and the reference light in such a superposed state to a recording medium, thereby recording the information on the recording medium. <P>COPYRIGHT: (C)2013,JPO&INPIT |
