A magnetic head suspension assembly is fabricated with an integral piece which includes a load beam section, a flexure section, a rest mount section and a leaf spring section between the load beam and rear mount. A tongue extends from the load beam to the flexure and has a down-facing load dimple which contacts the non-air bearing surface of an attached air bearing slider. The flexure includes narrow thin legs adjacent to a cutout that delineates the load beam tongue. The head suspension is characterised by a high first bending mode frequency and low pitch and roll stiffness.
