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.
