ABSTRACT:
An actuator and a method of operating an optical pickup of an optical disk drive comprises a blade on which an object lens is mounted, a plurality of magnets for generating a magnetic field, a plurality of focusing coils for interacting with the magnetic field generated at the magnets to move the blade in a first direction, a tracking coil for interacting with the magnetic field generated at the magnets to move the blade in a second direction, a first supporting member for supporting the blade so that the blade is tilted by the difference in electromagnetic forces which are generated between the magnets and the focusing coils, and a second supporting member connected to the first supporting member, for movably supporting the blade in the first and the second directions. Accordingly, the blade tilts in the tangential direction by adjusting the electric current supplied to the focusing coil.
