A pickup head actuator is disclosed. It is able to carry near-field optical I/O elements, far-field optical I/O lens, or magnetic I/O elements. Besides performing focusing and tracking servo, the attraction due to magnetic inductor and tracking magnet enables a base to float at different heights in its normal state, suitable for different types of I/O elements. Thus, the invention solves the problem of compatibility.
