摘要： This invention aims at reducing a rolling moment generated in coils mounted to lens holder side face without losing drive forces in a focusing direction and tracking direction in an objective lens drive of an optical pickup device. By shifting a coil line portion near the objective lens of two coil line portions substantially parallel to the tracking direction of the first coil in a direction departing from a lens optical axis, increase and decrease in drive forces generated in right and left first coils when the lens holder is moved in the tracking direction cancel each other so as to eliminate imbalance between the right and left drive forces.

摘要： It is an object of this invention to increase the rigidity of a movable part and decrease its weight. An objective lens driving apparatus has an objective lens which focuses light on the recording surface of an optical disk. The objective lens is driven by focusing coils in directions approaching and receding from the optical disk and is driven by tracking coils in the radial direction of the optical disk. The objective lens is held by a lens holder. A projecting part projecting outward from the outer side surfaces of the lens holder is formed around the entire peripheral edge of the bottom surface of the lens holder.
