    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.

    摘要： An optical information recording apparatus includes a first optical system that radiates an information beam that carries information onto a recording medium; a second optical system that radiates reference beams onto the recording medium; a radiation position specifying unit that specifies a plurality of recording spots positioned within a radiation range of the reference beams; and an incident angle obtaining unit that specifies an incident angle of the reference beams that is used for recording an i'th interference fringe into a second recording spot adjacent to a first recording spot, as a value obtained by adding a product of 1/(1+m) and an absolute value of a difference between an incident angle of a first reference beam used for recording an i'th interference fringe into the first recording spot and an incident angle of a second reference beam used for recording an (i+1)'th interference fringe into the first recording spot.
