摘要：
A lens actuator for use in an optical disk recording and reading apparatus includes a moving member and a mass balancing member. The moving member includes a holder for holding an object lens movably in tracking and focus directions, a driving coil for generating a thrust for driving the holder in the tracking and focus directions, and a set of supporting members for supporting the holder and supplying power to the driving coil. The mass balancing member is positioned diagonal to the object lens held on the moving member by the holder and is configured to make contact with the driving coil within the moving member.
