    • 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.
    • 提供了一种用于在光学记录介质中记录驻波信息并从光学记录介质再现驻波信息的光学记录/再现装置。 光学记录/再现装置设置有光学头,其将从光源(1)发射的一束激光分成三束,将分束的两束激光(A,B)输入到光学 盘(8)具有来自同一侧的反射平面(10)。 一个激光束(A)被辐射到达反射平面,另一个激光束(B)被辐射以被反射平面返回,然后通过使用一个激光束 物镜(7)。 通过由光头照射聚焦在相同聚焦位置(SF)的两个激光束,在光盘中记录驻波,当激光束(A)由光头照射时,从反射光读取信息 两个激光束被辐射。

    • Disclosed is a hologram recording method using a beam with a very large incident angle, a hologram reproduction apparatus using a holographic reflector, a hologram reproduction method using the same and a flat display element apparatus using a holographic reflector. The hologram recording method using a beam with a very large incident angle comprises the steps of generating a sheet beam as the reference beam, and introducing the reference beam into the recording medium at an incident angle of at least 70 DEG . The hologram reproduction apparatus using a holographic reflector comprises a light, a holographic reflector, an adjustor, and a hologram. Also, the hologram reproduction method using the hologram reproduction apparatus comprises the steps of irradiating a beam emitted from a light source as a reference beam to a holographic reflector, reflecting the reference beam illuminated to the holographic reflector therefrom to generate a reconstructed beam, and allowing the generated reconstructed beam as a reference beam to pass through a hologram to reproduce the hologram. The flat display element apparatus comprises a light source, a holographic reflector, an adjustor, and a flat display element.
