摘要： A laser power control apparatus is for use in an optical disk apparatus for recording information on an optical disk having at least a first layer and a second layer. The laser power control apparatus includes a power control section for controlling a laser element such that a power of a laser beam approaches a control target level; a change detection section for detecting that a recording condition for the optical disk has been changed; and a power adjustment section for adjusting the power of the laser beam for a recording film of the first layer, in accordance with an output from the change detection section. The power adjustment section determines the power of the laser beam for a recording film of the second layer, based on the power of the laser beam which has been adjusted for the recording film of the first layer.
