ACTUATOR FOR OPTICAL PICKUP DEVICE OF OPTICAL DISK DRIVE

摘要

An actuator for an optical pickup device 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 through which a current flows to interfere with the magnetic field generated by the magnets to move the blade in a first direction, a tracking coil through which a current flows to interfere with the magnetic field generated by the magnets to move the blade in a second direction, a first supporting member supporting the blade such that the blade tilts due to the difference between electromagnetic forces generated between the magnets and the respective focusing coils, and a second supporting member connected to the first supporting member to movably support the blade in the first and the second directions. Accordingly, by adjusting the current supplied to the focusing coils, the blade is tilted in a tangential direction.
