The actuator comprises of two magnetic elements, four metallic wires, a lens holder located between the two magnetic elements for holding a lens, and a planar coiling device affixed on the lens holder. The lens holder further comprises of at least one fixing part whose purpose is to connect with the four metallic wires and keep the lens holder at a hanging status. The planar coiling device further comprises of two focusing coils, two tracking coils and four separated bonding pads, two bonding pads located on each of the two surfaces of the planar coiling device for respectively connecting with the four metallic wires; two of the four bonding pads electrically connect to the two focusing coils and the other two bonding pads electrically connect to the two tracking coils.
