Abstract

In the lens driving apparatus of a disk player, a pair of magnets for generating magnetic fields are fixed to a pair of yokes , respectively to generate a magnetic gap therebetween. The pair of yokes are oppositely arranged on and fixed to a plate-like actuator base by plural screws through a fixing member . A movable portion is movably hung by four supporting wires (or plate screws) on a supporting base that is fixed to the actuator base . The movable portion is arranged within the above magnetic gap. In such a configuration, the apparatus for a disk player can shift a natural resonance frequency to a high frequency and can be operated at a high speed.
