ABSTRACT:
In a disk drive unit having disk clamp/spacer/hub flanges, impact protrusion features extend from an end of a load beam to limit slider displacement from disk surface. The impact features also compensate for stack-up of the E-block arm such that potential interference and collision between the suspension and flange is minimized, if not eliminated, thereby reducing the risk of generating debris. The impact features are etched and formed with the stiffening rails of an up-rail suspension while a dimple is formed onto a back side of the down rail or rail-less suspension, in a direction away from the slider.
