ABSTRACT:
A head suspension assembly includes a load beam, a flexure and a constraint structure for limiting range of motion of the flexure tongue. The constraint structure directly engages a free end of the flexure tongue to restrict the range of motion of the free end of the flexure tongue. This constraint structure is on the disk-confronting surface of the load beam to overlap the proximal end of the flexure tongue. The constraint structure may be formed in one piece with a proximal extension of the flexure.
A method for manufacturing a head suspension assembly of the type including a load beam and a flexure, includes a step of incorporating into the suspension assembly a constraint structure for directly engaging the free end of the flexure tongue to restrict the range of motion of the flexure tongue. Preferably, the method includes shaping the constraint structure from the flexure itself, and bending the constraint structure, so that the distal limit of the constraint extends directly over and is spaced from the free end of the tongue, between the tongue and its associated disk surface.
