Abstract
The present invention provides a tilt angle adjusting mechanism for adjusting the tilt angle of the optical axis of a pickup head relative to the optical disc. The pickup head is furnished with an elongated hole, a slot or an L-shape base, several pre-loaded pressing elements and adjusting elements for a three-point mounting on two guide rods. The adjusting elements make the optical pickup head rotatably on two axes so as to adjust the tilt angle. An adaptive mechanism can also be incorporated for adjusting the tilt angle of the pickup head without modifying the original structure of an optical disc driver.
