An optical pick-up actuator capable of a tilt operation. The optical pick-up actuator has a triaxial magnetic driving portion installed on a movable portion (20) and a supporting portion to move the movable portion in a focusing direction and a tracking direction and tilt the movable portion. The triaxial magnetic driving portion includes a pair of focusing/tilting driving magnets (41, 42), a pair of tracking driving magnets (43, 44), focusing coils (51,52), a pair of tilt coils (53, 54), and a pair of tracking coils (55, 56). The pair of tilt coils (53, 54) installed on the movable portion each face one of the pair of focusing/tilting driving magnets (41, 42) and are wired independently from the pair of focusing coils (51, 52). |
