Patent ID: 6898028

Claim:
An optical device for following a track ( 2 ) on a surface of an optically readable record carrier ( 3 ) to be incorporated therein, the device comprising: a lens ( 8 ); a relative displacement unit ( 10 ) which, during operation, is capable of supporting the record carrier ( 3 ) and of causing a relative displacement of the record carrier ( 3 ) with respect to the lens ( 8 ), the relative displacement in a first direction being parallel to the track ( 2 ) and in a first plane being parallel to the surface of the record carrier ( 3 ) to be incorporated; a slide ( 1 ) having a supporting face ( 6 ) which, during operation, is displaceable in a second direction transverse to the track ( 2 ) and along the surface of the record carrier ( 3 ) to be incorporated; a slide displacement unit ( 14 ) for displacing the slide in the second direction dependent on a slide position signal; and an actuator ( 4 ) comprising: a radial displacing means for positioning, during operation, the lens ( 8 ) in the second direction; a tilting means which is capable of tilting the lens ( 8 ) in a second plane transverse to the track ( 2 ) to be followed; a lens support ( 7 ) for supporting the lens ( 8 ); at least two connection elements ( 5 ) which are secured to the supporting face ( 6 ) of the slide ( 1 ) and to the lens support ( 7 ), characterized in that there is a mechanical coupling between the radial displacing means and the tilting means for tilting the lens ( 8 ) upon a displacement of the lens ( 8 ) in the second direction.
