<p>An optical reproducing apparatus in which reproduction of information is carried out by using an optical record carrier. In order to compensate a radial tilt between the surface of the record carrier and the objective lens, the objective lens is tilted. In the optical apparatus of the invention, the actuator of the radial displacement of the objective lens is used to also tilt the objective lens at the same time. A displacement of the objective lens in the radial direction by the actuator has a direct effect of tilting the objective lens. This is accomplished by a mechanical link between the radial displacement and the radial tilting. This has the advantage that there is no need for an extra tilt actuator to tilt the objective lens.</p> |
