  • Optical Pickup Actuator and Optical Scanning Device
    Publication number: 20080259766
    Abstract: An optical pickup actuator for low building height includes a suspended lensholder (101) with a lenssystem (102), focusing (106a, 106b, 106c 106d) and tracking coils (109) and magnets (107a, 107b, 107c) for cooperation with the focusing and tracking coils. The focusing and tracking coils may be arranged for tilting the lensholder in the actuator. The lowest entrance position for a radiation beam to enter a beam entrance (113) at a side of the actuator is not determined by the height and location of the coils.
