Objective lens driving device in an optical pickup

摘要

An objective lens driving device is disclosed, in which the objective lens is moved in the direction of the optical axis thereof by a thrusting force generated between a magnet for focusing and a driving coil for focusing to effect focusing and it is moved in the direction perpendicular to that of the optical axis thereof by another thrusting force generated between a magnet for tracking and a driving coil for tracking to effect tracking.
