Disk drive suspension and manufacturing method therefor

摘要

An actuator mounting section comprises a plate member includes a first plate and a second plate. The first plate is formed with an opening which accommodates an actuator element. The second plate comprises 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.

1. A disk drive suspension with an actuator element, comprising:
a first plate comprising: (i) an opening which accommodates the actuator element, (ii) a stationary part to which a first end of the actuator element is secured, and (iii) a movable part to which a second end of the actuator element is secured; a second plate comprising: (i) a main body portion which overlaps with the first plate thicknesswise, (ii) a plurality of supporting portions which support opposite ends of the actuator element, and (iii) a narrow portion whose width is less than a width of each of the plurality of supporting portions, wherein the narrow portion is formed between the main body portion and a corresponding one of the plurality of supporting portions; a weld seal portion which secures the first plate and the second plate together at the narrow portion and which seals a mating surface between the first plate and the second plate at the narrow portion; and an adhesive provided between the opposite ends of the actuator element and an inner surface of the opening.
