Patent ID: 7245563

Claim:
An optical pickup comprising: a movable base moving in radial directions of a disc-shaped recording medium, which is mounted to a disc table; and an objective lens drive device disposed at the movable base, wherein the objective lens drive device comprises a supporting block, a movable block, and a supporting spring, the movable block holding an objective lens and moving with respect to the supporting block in focusing directions and tracking direction, the focusing directions corresponding to directions in which the movable block moves into contact with and separates from a recording surface of the disc-shaped recording medium, the tracking directions corresponding to substantially radial directions of the disc-shaped recording medium, the supporting spring connecting the supporting block and the movable block, and wherein the supporting block comprises a stationary section, a supporting shaft, a tilt drive section, and a tilt magnetic circuit, the stationary section being secured to the movable base, an axial direction of the supporting shaft being perpendicular to the focusing directions and the tracking directions, the tilt drive section being rotatably supported at the stationary section through the supporting shaft and being connected to the movable block by the supporting spring, the tilt magnetic circuit rotating the tilt drive section with respect to the stationary section, and further comprising a flexible printed circuit board for supplying electrical power to the focusing coil, tracking coil, and tilt coil, the flexible printed circuit board comprising an extending section disposed on the tilt drive section and extending in the tracking directions, wherein at least a portion of the extending section is not secured to the tilt drive section.
