Abstract
An optical pickup actuator includes focus coils, track coils, and tilt coils disposed on opposite sides of a bobbin to drive the bobbin in a focus direction, a track direction, and a tilt direction and leaves the other opposite sides of the bobbin as empty sides on which the focus, track, and tilt coils are not disposed. The optical pickup actuator includes a base, a bobbin, a holder, and a magnetic driver. The bobbin is movably disposed on the base since supporting units support the bobbin above the base. The holder is disposed on one side of the base and connected to one ends of the supporting units. The magnetic driver has the focus coils driving the bobbin in the focus direction, the track coils driving the bobbin in the track direction, the tilt coils driving the bobbin in a tilt direction, and magnets installed to face the focus coils, the track coils, and the tilt coils. Since the other opposite sides are not mounted with the focus, track, and tilt coils, wires of the support units can easily be installed on the other opposite sides of the bobbin.
