| Abstract | In an objective lens drive apparatus for driving a body to be driven including an objective lenses in the focusing direction along the optical axis and in the tracking direction perpendicular to the optical axis, there is provided an adjuster for allowing the center of a driving force exerted on the body in the tracking direction to coincide with the center of gravity of the body or to shift the center of gravity farther away from the objective lenses from the driving force along the optical axis of the objective lenses. |
