摘要：An optical information processing apparatus is provided. The optical

information processing apparatus includes: an optical system which irradiates a referencebeam on an optical information recording medium having a plurality of recording regionsadjacent to each other so that the reference beam is wider than each of the recordingregions; a filter which filters readout beams reproduced from the optical informationrecording medium to pass a selected readout beam reproduced from a selectedrecording region and separates neighborhood readout beams reproduced from

neighborhood of the selected recording regions; a readout beam detector which detectsthe selected readout beam passing through the filter; a neighborhood readout beamdetector which detects the neighborhood readout beams separated by the filter; and acontroller which compares the neighborhood readout beams detected by theneighborhood readout beam detector to control a reproduction condition of theselected readout beam.
