PURPOSE: An optical pickup available for tilt control in radial and tangential directions is provided to perform high-precision focusing by correcting tilt error in radial and tangential directions. CONSTITUTION: An optical pickup available for tilt control in radial and tangential directions consists of a bobbin(4) protecting and supporting an objective lens(1); a focusing control coil(2) moving the objective lens toward an optical disk vertically; a tracking control coil(3) moving the objective lens in the horizontal direction of the optical disk; magnets(6) arranged opposite to the focusing control coil and the tracking control coil; and a mounting plate(7) formed vertically to a base plate(5) to support a support bar. If tilt error is generated in radial and tangential directions, power is supplied via a flexible PCB(Printed Circuit Board,10). Therefore, the tilt error is corrected in the radial and tangential directions by magnetic force with the magnets.
