The optical pick-up actuator has a triaxial magnetic driving portion installed on a movable portion 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, a pair of tracking driving magnets, focusing coils, a pair of tilt coils, and a pair of tracking coils. The pair of tilt coils installed on the movable portion each face one of the pair of focusing/tilting driving magnets and are wired independently from the pair of focusing coils.
