PROBLEM TO BE SOLVED: To prevent the deterioration of a reproducing characteristic caused by the influence of deflection on a magneto-optical disk. SOLUTION: For the signal recording area of a magneto-optical disk 1, reproducing power calibration is carried out in innermost and outermost peripheral side positions and, based on obtained reproducing power and reproducing power in an intermediate position is obtained from curve approximation, and set. |
