Flexure with Trapezoid Holes

      Disclosed is a flexure design of a suspension assembly used in
hard disk drives.

      Recently, slider size has become smaller.  In order to utilize
such smaller sliders, it is necessary to shrink the flexure size,
too.  If these kinds of smaller sliders and shrinked flexures are
used, the bonding area and quantity of adhesives between flexures and
sliders will decrease.  As a result, bonding strength will degrade.

      In some cases, a flexure with some holes may be used to improve
bonding strength.  Usually those holes are cylindrical shaped.

      In order to improve bonding strength further, a different shape
of hole on flexure is proposed.

      The Figure shows two examples of the hole shapes (section
view).  By changing the diameters of the top and bottom holes, the
quantity of adhesives between a flexure and a slider can be
increased,
and bonding strength is improved.
