    摘要: An optical recording/reproducing apparatus includes an optical recording medium in which a holograms are recorded depending on an incident angle of a reference beam. The reference beam is irradiated to holograms while changing the incident angle to generate a reproduction light beam, and an image patterns are detected by an image pattern detector. The continuously output reproduction image patterns are temporarily stored in an image recorder, and the maximum value of reproduction light intensity is detected to generate a trigger signal. Depending on the trigger signal, an optimal image pattern is extracted from continuous reproduction image patterns, and thus, two-dimensional data is decoded.
