Abstract: An actuator mounting section includes a plate member including a first plate and a second plate. The first plate is formed with an opening which accommodates an actuator element. The second plate includes a main body portion which overlaps the first plate and supporting portions which support opposite ends of the actuator element. A narrow portion narrower than the first plate is formed at a part of the main body portion of the second plate. A weld seal portion is formed by laser-welding the first plate and the second plate at the narrow portion. Adhesive is provided between the opposite ends of the actuator element and an inner surface of the opening of the first plate.

Abstract: A head driving device includes a base member, a head supporting member, a beam member, a piezoelectric unit, and a reinforcement member. The reinforcement member includes a first portion and a second portion. The first portion is arranged between a first end portion in a length direction of a head member and the base member. The second member is arranged between a second end portion in a length direction of the head member and the base member. The reinforcement member allows the head supporting member to move in a direction along a surface of tape and controls the head supporting member from moving in a thickness direction of the head member.
