OPTICAL INFORMATION RECORDING/ REPRODUCING APPARATUS, OPTICAL INFORMATION RECORDING/ REPRODUCING METHOD, AND OPTICAL INFORMATION RECORDING MEDIUM |
摘要 |
In an optical information recording/reproducing apparatus using holography, there are provided the optical information recording/reproducing apparatus, method thereof, and optical information recording medium which correct a zero point and variation of unit quantity of a reference beam angle between apparatus and perform recording or reproducing operation with high compatibility between apparatus. 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 based on the detection angle information.
