ABSTRACT:
A rotating disk type information storage apparatus includes a rotating disk for storing information, a head for writing/reading the information, a support member for supporting the head, a first actuator for moving the support member to a predetermined position on the rotating disk, and a second actuator including a movable member supported by the support member and capable of being rotated about an axis perpendicular to a recording surface of the rotating disk, and a driving force generating member for rotating the movable member. The movable member is integrated with the support member and has the head mounted thereto, in which a center of gravity of the movable member including the mounted members generally coincides with the center of rotation of the movable member. The second actuator corrects an error in a positioning of the support member and positions the head, and the movable member is not vibrated during the positioning.
