ABSTRACT:
There is provided a method of annealing an optical recording medium formed on a substrate having a land and a groove, comprising the steps of: annealing one side wall between the land and the groove with a predetermined laser power; moving the laser to another side wall by allowing the laser to traverse one of the land and the groove with a laser power for not annealing after the step of annealing is conducted; and annealing the another side wall with the laser power.
