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.
