ABSTRACT:
A method is disclosed for adjusting write power when recording an optical disc. First, pre-setting a range of a write quality parameter and a write power. Next, moving a spindle motor and an optical pickup head to a target track. After the spindle motor is stable at the intended rotation speed as well as the optical pickup head is positioned correctly at the target track, then reading a write quality parameter. Then, determining whether the write quality parameter is in the range. When the write quality parameter is in the range, then according to the write power to write data to the target track. When the write quality parameter is out of the range, then adjusting the write power to write data to the target track.
