Abstract
An optical actuator is disclosed for positioning a lens to focus a laser light on a surface of a member, such as on optical disk, with minimum lens tilt error. The optical actuator includes a lens mount for supporting the lens, and at least two spaced-apart flexures that are fixed to the lens mount. The flexures are arranged so that they are parallel when viewed from one side. The optical actuator further includes a structure for 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 to focus the light beam, lens tilt error is minimized.
