Abstract
The present invention is smart burn method for optical drives. When the laser pick-up head bears great oscillations along the vertical and horizontal directions, the laser light cannot focus on the track accurately that causes the failure of writing. The present invention proposes a re-link method employing a technique of controlling focus error signal, tracking error signal, or both, and capable of automatically reducing the writing speed of an optical drive while detecting an occurrence of a preset burn-error parameter is being exceeded, such that a stable and good writing quality can be achieved.
