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.

Tilt angle adjusting mechanism for optical pickup head

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 tilt angle adjusting mechanism includes two guide rods supported by a fixed holder and an adjusting holder. The adjusting holder receives an adjusting element for adjusting the guide rod moving toward or away from the optical disc. By adjusting one or both adjusting elements to move the guide rods in different axes, the correct tilt angle can be attained.
