An optical recording/reproducing device is provided for recording standing wave information in an optical recording medium and reproducing the standing wave information from the optical recording medium. The optical recording/reproducing device is provided with an optical head, which splits one beam of laser light emitted from a light source (1) into three beams, inputs two beams of laser light (A, B) of the split beams to an optical disc (8) having a reflecting plane (10) from the same side. The one laser beam (A) is radiated to reach the reflecting plane, and the other laser beam (B) is radiated to return by the reflecting plane, and then, the beams are focused at the same focus position (SF) by using an objective lens (7). A standing wave is recorded in the optical disc in layers by the two laser beams radiated to be focused at the same focus position (SF) by the optical head, and information is read from the reflected light when the laser beam (A) of the two laser beams is radiated.
