Paper Abstract

An optical recording static tester with high performance but low cost based on a commercial optical disk drive is introduced. Its schematic diagram and optical system are described. A quasi-linear-region focusing search method is proposed and carried out. It is a simple reliable focusing search method based on the positive and negative feedback characteristics of the focusing error curve.
