摘要： An optical beam (104) emitted from a laser light source (105) is converted by a spatial filter (106) to have a desired beam diameter, and converted by a collimate lens (107) into a collimated beam. The optical beam (104) rendered to be a collimated beam has its intensity adjusted by an ND filter (128) The optical beam (104) having its intensity adjusted is lead by a mirror (109) to an angle rotation mirror (101). The angle rotation mirror (101) reflects the optical beam (104) toward a hologram element (102). Holograms are recorded on the hologram element (102) in advance, so that reconstructed beams (103a-103c) are collected at a prescribed position irrespective of an incident position of the optical beam (104).

摘要： [PROBLEMS] To provide a search method capable of effectively searching for information. [MEANS FOR SOLVING PROBLEMS] A search light (21) is generated from a search condition (S1). The search light is applied to a hologram (104a) recorded on a hologram recording layer (104) (S2). When a reproduction light (22) is generated by interference between the search light and the hologram, address information on the hologram which has generated the reproduction light is identified by using an address light (23) for reading address information and the address information identified is recorded (S3). When no reproduction light (22) is generated from the hologram by the search light, the search light is applied to another hologram (104b) recorded on the hologram recording layer.

摘要： An optical disc apparatus can highly accurately record a hologram representing information on or reproduce such a hologram from an optical disc. When recording information on an optical disc 100, the optical disc apparatus controls the position of an objective lens OL1 according to the outcome of detection of a red reflected light beam Lr2 so as to make the focus Fr thereof follow a target track and it also makes the focus Fb1 of a blue light beam Lb1 agree with a target mark position by the objective lens OL1 and also the focus Fb2 agree with the target mark position by controlling the position of another objective lens OL2 according to the outcome of detection of the blue light beam Lb1 by way of the objective lenses OL1 and OL2 so as to make the focus Fb1 of the blue light beam Lb1 and the focus Fb2 of the blue light beam Lb2 agree with the target mark position and the blue light beam Lb1 and the blue light beam Lb2 interfere with each other. Thus, as a result, the optical disc apparatus can record a recording mark RM at the target mark position.

摘要： 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.
