Offset Head Suspension Assembly for Low Profile

      Disclosed is an offset head suspension assembly (HSA) structure
for reducing its height.  As shown in Fig. 1, a load beam and a
flexure that incorporate offset structure respectively are put
together and can reduce the HSA height.

      Fig. 2 illustrates the height of the offset head suspension
assembly (HSA) structure according to the present invention.

      Fig. 3 shows several types of offset flexure as well as
conventional ones with and without sliders.  The two types of offset
flexure from the bottom, that is, Offset-Wedge and Offset-Arc type,
are preferred embodiment of the offset flexure structure of the
invention.

      Fig. 4 explains the logical background of the preferred
embodiments of the offset flexure structure.  The hatched portion is
a cantilever area and it generates both a pitch and a roll stiffness.
The Offset-Straight type is the simplest application of the offset
flexure structure, but the straight offset creates a rotational axis
and makes a slider easily rotate to a pitch direction.

      On the other hand, the two preferred embodiments do not create
a redundant rotation axis and can maintain the equivalent flexure
stiffness to a pitch movement like a conventional flexure holds.
