Optical scanning device, mirror objective suitable for use therein and an optical recording and/or reproducing apparatus provided therewith. |
摘要 |
<p>A scanning device for an optical recording and/or reproducing apparatus comprises an objective system which is composed of reflectors (33, 35) arranged on the surface of a transparent body (30). Since the reflectors both focus the radiation beam (20) and fold it within the body (30), a very compact write and/or read unit is obtained. The scanning device may also be given a very robust and stable form by fixing the radiation source (40) and the detection system (60) to the surface of the transparent body (30).</p> |
