发明名称 Lens driving device and optical pickup using the lens driving device
摘要 In a lens driving device for an optical recording/reproducing apparatus, a lens is held by a platelike damping member that is made of silicone porous material, for example, and both ends of the damping member are fixed to a base. This construction prevents undesired oscillations. Also, in order to drive the lens, two magnets are attached to an outer edge of the lens opposite to each other with the lens interposed in between them, and driving coils are attached to the base facing the magnets. The driving coils have two coils that drive the lens in the tracking and focusing directions, respectively.
