An optical pickup actuator for low building height includes a suspended lensholder ( 101 ) with a lenssystem ( 102 ), focusing ( 106 a , 106 b , 106 c 106 d) and tracking coils ( 109 ) and magnets ( 107 a , 107 b , 107 c) 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.
