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.
Claims5
A disk drive suspension having a pair of actuator elements, the disk drive suspension comprising:
- a first plate comprising:
- (i) a pair of openings each of which accommodates a respective one of the pair of actuator elements, (ii) a stationary part to which a first end of each of the actuator elements is secured, (iii) a movable part to which a second end of each of the actuator elements is secured, and (iv) a bridge portion formed between the pair of openings and connecting the stationary part and the movable part;
- a second plate comprising:
- (i) a main body portion which overlaps with the first plate thicknesswise, (ii) supporting portions which support opposite ends of each of the actuator elements, (iii) a bridge part overlapping the bridge portion, and (iv) narrow portions formed at both ends of the bridge part and being narrower than the bridge portion;
- a weld seal portion which fixes the first plate and the second plate together and which seals a mating surface between the first plate and the second plate at the narrow portions;
- and
- adhesives respectively provided between the opposite ends of the actuator elements and inner surfaces of the openings.
