Abstract

Nonlinear friction on a pickup head mechanism causes an objective lens shift. Detrack that causes the objective lens shift makes deteriorates read signal quality. To reduce the objective lens shift, we implement a nonlinear friction compensator in the pickup head. Experimental results confirm this compensator reduces the objective lens shift a quarter of not used.
