Patent attributes
The present invention is directed to an optical pick-up apparatus used for recording/reproduction of an optical disk, which comprises an optical pick-up (17) caused to undergo feed operation in the radial direction of optical disk (2), and for performing write or read operation of information signals with respect to the rotating optical disk, and a flexible printed wiring board (45) having one end portion (45a) connected to the optical pick-up, and the other end portion (45d) provided in a manner extended in the feed direction of the optical pick-up. The flexible printed wiring board includes a folded portion (45g) folded back toward the bottom surface portion side of the optical pick-up, and a bending displacement portion (45h) for allowing folded position of the folded portion to undergo displacement in a manner following the feed operation of the optical pick-up, wherein a slit (47) for escaping a projected portion (17b) projected from the bottom surface portion of the optical pick-up is provided at the folded portion.
