ABSTRACT:
An objective lens driver and an optical memory device with the respective polarities of magnetic circuits used for the focusing and tracking operations are set such that a repulsive force works in a direction opposing the gravitational force. Respective differing polarities of a pair of magnetic circuits used for focusing face each other, and respective differing polarities of a pair of magnetic circuits used for tracking also face each other.
