PROBLEM TO BE SOLVED: To provide an optical pickup device capable of simply inclining a lens holder in setting control action for detecting and correcting an optical offset component.SOLUTION: In setting control performed whenever an optical disc D is loaded, a lens holder 15 energized by a tracking coil Ct is moved in a radial direction (Rad), and then the lens holder 15 energized by a focus coil Cf is moved downward. At this time, a lower contact part 15b of the lens holder 15 touches a regulation part 7 and the lens holder 15 is inclined. In this state, an offset component due to random light can be accurately detected without receiving return light by a photo detector even when detection light is focused on a surface Ds of the optical disc D. |
