摘要：
A lens actuator for an optical disc storage device including a base; a lens holder assembly movably mounted to said base; said lens holder assembly comprising a lens holder with a single surface-field magnet and a lens mounted thereon; a single surface-field coil set mounted to said base parallel to and proximate said surface-field magnet; whereby a current introduced in a coil of said coil set produces a net magnetic force having a resultant line of action passing through said lens holder assembly.
