<p><P>PROBLEM TO BE SOLVED: To achieve a higher recording density by changing the size or shape of page data for each recording angle when angle-multiplexing recording is performed. <P>SOLUTION: An optical information recording apparatus includes: a spatial light modulator 101 which converts illuminating light emitted from a light source into a plurality of partial information light beams by passing the illuminating light through a plurality of modulation regions; optical mechanisms 102, 103, and 104 which converge the partial information light beams to a holographic memory recording medium 110, and irradiate the holographic memory recording medium 110 with reference light so that the reference beam intersects the partial information light beams at an information recording layer; an actuator 140 which drives the holographic memory recording medium 110, and a controller 130 which performs angle-multiplexing recording of information by emitting illuminating light from the light source while driving the holographic memory recording medium 110, and carrying the information by switching each of the plurality of modulation regions. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
