METHOD FOR EVALUATING REPRODUCTION LIGHT ENDURANCE OF OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently (simply, speedily, and precisely) evaluating the reproduction light endurance of an optical recording medium in which the recording layer is deteriorated due to irradiation with reproduction light.

SOLUTION: The method for evaluating the reproduction light endurance of the optical recording medium in which the recording layer is deteriorated due to the irradiation with the reproduction light includes a measurement step and an estimation step. The measurement step measures reflectivity before recording and measures reflectivity after recording with predetermined recording power. The estimation step estimates the reproduction light durability on the basis of the measured reflectivity before recording and the measured reflectivity after recording.
