Abstract
This paper relates to blue laser optical storage technology, particularly the servo system focus point search problem. The article presents a description of the focusing problem and proposes a new adaptive algorithm to prevent physical damage to the optical disc and pick-up head. The adaptive algorithm also reduces focus point access time.
