OPTICAL INFORMATION RECORDING/REPRODUCTION DEVICE AND METHOD

摘要

[PROBLEMS] To provide an optical information recording device, reproduction device, and method capable of recording and reproducing information more accurately in holographic recording and reproduction. [MEANS FOR SOLVING THE PROBLEMS] An optical information recording device includes a first spatial light modulator (I) for spatially modulating light from a light source (143) by a plurality of pixels so as to generate information light and a second spatial light modulator (R) for spatially modulating the light from the light source by a plurality of pixels so as to generate reference light. The area I of the information light and the area R of the reference light on the entrance pupil surface of an objective lens (111) are formed in such a manner that one of the areas surrounds the other area. The reference light is spatially modulated by the second spatial light modulator (R) so that no interference is generated between the reference lights on the information recording layer 3.
