Abstract

PURPOSE:To make the device of pickup including the light source small in size and light in weight, by using the semiconductor diode laser for the light source. CONSTITUTION:The 1st elastic plane 1a in parallel with the video disc record and the 2nd elastic plane 2b vertical to the disc are formed intergrally with the elastic supporting plate. The focus coil 5 is fixed to the lower surface of the moving holder 3 fixing the 1st elastic plane 1a, and the side plane is fixed to the tracking coil. To the fixed block 2 fixing the 2nd elastic plane 2b, the focussing field member 6 and the tracking field member 8 are fixed, and the tracking motor 9 is fixed. The pickup 4 is controlled at correct position in optical axis and track axis directions with the focus detection output obtained from the pickup 4 and the tracking detection output.
