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.
