An apparatus is disclosed for driving a lens for use with a disk player to avoid the swing movement of a movable member without the degradation of the sensitivity of an actuator. The apparatus includes magnetic flux producing elements for providing magnetic flux to tracking coils fixed to a lens holder parallel to a focusing direction. The magnetic flux producing elements provide a first magnetic flux to a first area of the coil and a second magnetic flux to a second area of the coil. The first magnetic flux has a direction opposite to that of the second magnetic flux. At least a portion of a boundary surface between the first and the second areas is inclined from a focus direction of the lens. <IMAGE> |
