A first bearing at one end of a mechanism section on which an optical head is mounted is fitted into a first fixed rail and supported slidably, and a second bearing at the other end is movably supported on a second fixed rail located parallel to the first fixed rail with a gap in a direction perpendicular to the moving direction, and by a driving means located between both the fixed rails, By moving the mechanical section along both of the fixed rails, the optical head mounted on the mechanical section is driven and movable relative to the bar-shaped magnet fixedly arranged along the fixed rails. attaching the engaged coil to the mechanism section;
When the mechanism section moves along the fixed rail, the moving speed and position of the optical head mounted on the mechanism section are known from the current induced in the coil, and the moving speed and position of the optical head mounted on the mechanism section are determined to match the direction of gravity of the mechanism section. Means for exerting an attractive force between the coil attached to the mechanism part and the rod-shaped magnet in a direction such that the first bearing is an oil-impregnated bearing, and the second bearing is a rolling bearing. optical head drive device. 2. In claim 1, all or a part of the constituent material of the mechanism section on which the optical head is mounted is made of a lightweight material such as a plastic molding material, so that the center of gravity of the mechanism section is located at the first point. An optical head drive device that allows movement toward the bearing side and reduces overall weight.
