ABSTRACT:
An optical reading or writing actuator for directing a laser beam for reading or writing an optical medium including a base and an actuator assembly having an objective lens fixed in the assembly and flexures for supporting the actuator assembly for movement in focus and tracking directions to position the objective lens. The actuator further includes at least one sensor disposed relative to the actuator assembly for producing an output tracking position signal and a beam splitter positioned relative to the actuator assembly and the sensor for directing a portion of the laser beam to the sensor and for directing another portion of the laser beam to the objective lens which focuses it on the optical medium.
