OPTICAL INFORMATION RECORDING/REPRODUCING APPARATUS, OPTICAL INFORMATION RECORDING/REPRODUCING METHOD, AND OPTICAL INFORMATION RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an optical information recording/reproducing apparatus using holography, which corrects a zero point and variation of unit quantity of a reference beam angle between apparatuses and performs recording or reproducing operation with high compatibility between apparatuses; an optical information recording/reproducing method; and an optical information recording medium.

SOLUTION: The optical information recording/reproducing apparatus detects a reference beam angle suitable to reproduce angle correction data recorded on the optical information recording medium and corrects a zero point and unit quantity of the reference beam angle at the time of recording or reproducing operation on the basis of the detection angle information.
