  • Actuator which compensates for compact disk tilt error
    Patent number: 5724197
    Abstract: An optical actuator for positioning a lens to focus a laser light beam on a surface of a compact disk, and to compensate for tilt errors in the surface of the compact disk, including a lens mount for supporting the lens; a base; at least two pairs of spaced-apart flexures, each pair of flexures being fixed to the lens mount and to a base, the flexures of one pair being arranged so that they are non-parallel when viewed from the side and the distance between flexures at the base is less than the distance at the position where they are mounted to the lens mount and the other pair of flexures being arranged so that they are non-parallel when viewed from the side and the distance between flexures at the base is greater than the distance at the position where they are mounted to the lens mount; and applying a force to the lens mount along a line and between the flexures so that when viewed from the parallel flexure side the line bisects each flexure to cause the flexures to deflect such that as the lens moves in a
