摘要：An optical information processing apparatus is provided. The optical information processing apparatus includes: an optical system which irradiates a reference beam on an optical information recording medium having a plurality of recording regions adjacent to each other so that the reference beam is wider than each of the recording regions; a filter which filters readout beams reproduced from the optical information recording medium to pass a selected readout beam reproduced from a selected recording region and separates neighborhood readout beams reproduced from neighborhood of the selected recording regions; a readout beam detector which detects the selected readout beam passing through the filter; a neighborhood readout beam detector which detects the neighborhood readout beams separated by the filter; and a controller which compares the neighborhood readout beams detected by the neighborhood readout beam detector to control a reproduction condition of the selected readout beam.
