ABSTRACT:
An actuator for a digital versatile disc player which includes a lens holder to which object lenses are mounted, a tracking coil which is attached to an outer surface of the lens holder for tracking the lens holder, a focusing coil which is attached to the outer surface of the lens holder for focusing the lens holder, a yoke plate which magnetically interacts with the tracking and focusing coils, and supporting portions which movably support the lens holder, and to which the yoke plates are mounted. The supporting portions include a plurality of magnets and a pair of suspension plates, and the lens holder is floated with respect to the yoke plate by repelling forces between the magnets. The tracking and focusing functions are smoothly accomplished and external impacts are effectively absorbed by the floating of the suspension plates which support the lens holder.
