INITIALIZING METHOD FOR OPTICAL RECORDING MEDIUM, OPTICAL RECORDING MEDIUM AND INITIALIZING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress small non-uniformity in a reflection factor after initialization. SOLUTION: In the initializing method for a phase change type optical recording medium 1, the intensity of laser light on at least one end in the lengthwise direction of a laser spot irradiated with the laser Light by an LD 6 is made smaller than the intensity of light in the center of lengthwise direction of the laser spot.
