Abstract
A head suspension load beam for a disk file has a slender base portion shaped like a plate, one end of which is secured to a head actuator arm, and the other end of which supports a head. The base portion is reinforced by bending a side margin portion in the longitudinal direction of the base portion at substantially right angles to the plane of the base portion, and further by providing reinforcement ribs, the height of which does not exceed the height of the bent side margin portion, almost parallel to the side margin portion. A head suspension load beam of another embodiment of this invention is reinforced by bending the side margin portion substantially parallel with the plane of the base portion or further toward the plane of the base portion, instead of using reinforcement ribs.
