Device for recording optical disc and method therefor

摘要

A device for recording an optical disc and a method thereof, which can maintain a constant recording quality when information is recorded on an optical disc rotating at a given speed. The device for recording an optical disc includes a linear velocity detector (3) for detecting a linear velocity that is a relative velocity of a spot of a light relative to the optical disc on which the spot is irradiated to record the information, said velocity being measured in a tangential direction of a circumference of the optical disc; and an optical power controller (1) for controlling the optical power irradiated to record the information on the surface of the optical disc based on the linear velocity detected by the linear velocity detector. <IMAGE>
