PURPOSE:To make physical control operation of a pickup element for video disc use accurate, by providing physical driving means having different members at both ends of a cantilever member. CONSTITUTION:A cantilever member 50 provided along a plane of a base 40 is formed into a channel-shape groove, and magnets 54, 55 are fixed at both ends lengthwise. A through-opening 51 is formed at almost the center in the longitudinal direction of the cantilever 50. At the back of the member 50, dampers 52, 53 are fitted at both sides of the opening 51 with adhesives, respectively. The cantilever memeber 50 is elastically at the middle of the base 40 by leaving a suitable interval by using this damper. |
