ABSTRACT:
A scanning device for an optical disc record carrier includes a turntable and a positioning device which is movable relative to the turntable in a plane transverse to the axis of rotation thereof. The positioning device includes a radiation source unit and an actuator unit having a carrier which supports several different objective lenses and which is movable parallel to the access of rotation. The scanning device further includes actuating apparatus for moving the actuator unit and the radiation source unit relative to one another between discrete operating positions in at least the plane transverse to the axis of rotation, so as to place a respective lens in position for scanning a respective one of several different types of optical discs having mutually different substrate thicknesses and/or information densities.
