Abstract
An objective lens actuator drives an objective lens in a radial direction of a disklike recording medium parallel to a face of the recording medium and in a direction of an optical axis vertical to the face of the recording medium such that information can be optically written on or read from the recording medium. The objective lens actuator includes a substantially U-shaped lens holder at an approximately central portion of which the objective lens is supported, a pair of drive members for driving the lens holder, which are provided at opposite end portions of the lens holder, respectively, a base member, and four rodlike elastic members supporting the lens holder. Each of the elastic members has one end fixed to the base member. The other end of each of two of the elastic members is fixed to a distal portion of a first leg of the lens holder adjacent the base member. The other end of each of the other two elastic members is fixed to a proximal portion of a second leg of the lens holder remote from the base member.
