Abstract
A head gimbal assembly (HGA), such as for a hard disk drive (HDD), includes a load beam formed with a deck and side rails extending away from each lateral edge of the deck in a direction away from a corresponding flexure, where each side rail portion includes a limiter structure extending from the side rail in a direction toward the flexure, the limiter structure including a hooking portion positioned on a distal side of the flexure for limiting displacement of the flexure in a direction away from the load beam. As an integral part of the load beam, the limiters do not adversely impact the existing gimbal dynamic performance designed to enable high areal density HDDs.
