Abstract: A head actuator has two of arms that extend from a bearing assembly, and a relay FPC is fixed to each arm. The relay FPC extends from a head to the proximal end portion of the arm. The relay FPC includes a connecting portion located on the proximal end portion of the corresponding arm and has a first contact each. The connecting portions are opposed to each other across a space and form a female connector. A male connector attached to a main FPC has a projection detachably fitted in the female connector and second contacts provided on the projection and connected to the main FPC. As the projection of the male connector is fitted between the connecting portions of the female connector, the first and second contacts are pressed against each other, whereupon the relay FPC and the main FPC are connected electrically to each other.
