ABSTRACT:
An optical pickup actuator including a blade supported by a plurality of suspensions to be movable with respect to a base and a magnetic circuit to drive a movable part including the blade, a method of manufacturing the optical pickup actuator, an optical pickup employing the optical pickup actuator, and an optical recording and/or reproducing apparatus employing the optical pickup. The movable part includes a weight center adjusting element of the movable part in order to induce a radial rolling operation in a direction in which an optical axis of an objective lens is perpendicular to an information storage surface of an information storage medium, during a focusing operation in a high frequency band above the first resonant frequency of the optical pickup actuator. The method of manufacturing the optical pickup actuator includes checking the direction of radial rolling for each focusing driving frequency and adjusting the center of weight of the movable part when the direction of radial rolling is not the desired direction, and the center of weight of the movable part is adjusted until radial rolling is induced in a direction in which an optical axis of an objective lens is perpendicular to an information storage surface of an information storage medium.
