Abstract: An object lens driving apparatus (100) includes a lens holder (4) that holds an object lens (1) facing a recording medium and is so supported that the lens holder (4) is movable toward and away from the surface of the recording medium. A focusing coil (5) is fixed in the interior of the lens holder (4) so that the focusing coil (5) surrounds an optical axis of the object lens (1). By apply current to the focusing coil (5), a driving force is generated, which moves the lens holder (4) toward and away from the surface of the recording medium. By disposing the focusing coil (5) in the interior of the lens holder (4) so that the focusing coil (5) surrounds the optical axis of the object lens (1), a movable part of the object lens driving apparatus (100) can be reduced in size and weight, so that a high sensitivity can be accomplished.

Abstract: An objective lens driving apparatus includes a lens holder 1 that holds an objective lens 2, and a stationary base 9 that supports the lens holder 1 by a support shaft 3 parallel to an optical axis of the objective lens 2. A stationary yoke 11 and the magnet 8 are mounted to the stationary base 9. A focusing coil 4 and the tracking coils 5a and 5b are mounted to the lens holder 1. The interaction between the current in the focusing coil 4 and the magnetic field caused by the magnet 8 generates an electromagnetic force that moves the lens holder 1 along the support shaft 3. The interaction between the current in the tracking coils 5a and 5b and the magnetic field caused by the magnet 8 generates an electromagnetic force that rotates the lens holder 1 about the support shaft 3.
