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. The pick-up base displacement mechanism includes a screw which vertically passes through the second end of the pick-up base such that a lower end portion of the screw which protrudes from the bottom surface of the pick-up base is in contact with a sliding surface which is positioned a prescribed distance below the bottom surface of the second end of the pick-up, whereby the pick-up base can be displaced by adjusting the protruding length of the lower end portion of the screw to achieve tangential skew adjustment.
