ABSTRACT:
An optical apparatus is described for scanning an optical record carrier comprising a radiation source supplying a scanning beam, a reflector for directing the scanning beam to the record carrier and an objective lens for focussing the beam to a scanning spot on the information surface . The mounting height of the apparatus is considerably reduced by integrating the objective lens and the reflector in a single reflector-objective element.
