Abstract: A holographic optical information recording/reproducing device is provided with a laser light source 1 and a polarizing beam splitter 8 for splitting a light from the laser light source 1. At the time of recording information, one of light beams split by the polarizing beam splitter 8 is modulated by a spatial light modulating element 2 to form a beam array, which becomes a signal light 25, whereas the other split light beam becomes a reference light 22. Interference fringes generated by the signal light 25 and the reference light 22 are recorded as holograms in a holographic disc 5. At the time of reproducing the information, only the reference light 22 is irradiated to the holographic disc 5 and its diffracted light is detected. At this time, the holographic optical information recording/reproducing device makes the power of the reference light 22 in the holographic disc 5 for information reproduction larger than a sum of the power of the reference light 22 and the power of the signal light 25 in the holographic disc 5 for information recording.
