Abstract: A skew adjustment mechanism for an optical pick-up used in an optical disc drive is disclosed, in which the optical pick-up is freely movable in a radial direction of an optical disc along a guide rod for playing back or recording and playing back information recorded on the optical disc. The optical pick-up includes a pick-up base having a first end and a second end opposite to the first end, the first end being slidably connected to the guide rod. The tangential skew adjustment mechanism includes a pick-up base displacement mechanism provided on the second end of the pick-up base for rotationally displacing the pick-up base about an axis of the guide rod.

Abstract: A disk device includes a drive mechanism having at least a disk motor and an optical head, the disk motor rotating a recording disk, and the optical head accessing the disk to reproduce information from the disk and/or record information in the disk. A first printed circuit board controls the disk motor and the optical head of the drive mechanism, the first printed circuit board receiving signals from the optical head and/or sending signals to the optical head to perform the reproducing of information and/or the recording of information. The disk device further comprises a second printed circuit board electrically coupling the drive mechanism to the first printed circuit board, the second printed circuit board including a connector coupled to wire patterns of the signals received and/or sent by the first printed circuit board, and the connector being coupled to the first printed circuit board.
