Head Suspension Assembly with Extended Mount Plate

      Disclosed is a new Mount Plate design of an Head Suspension
Assembly (HSA) for good load force stability used in Hard Disk Drives
(HDD) by swaging process.

      Usually an HSA is attached to a carriage by swage process.
Swage is the caulking structure that the Mount Plate boss is deformed
through a swage ball.  In the swaging process, we need to align each
HSA very tightly.  It can be achieved by passing through the
Alignment Pin into the holes of the HSAs shown in Fig. 1.  However,
because the HSAs are fragile, they may damage when the pin is
inserted.  Such kind of damage causes degradation of Load Force.

      In order to eliminate this kind of degradation, an elongated
hole is made on the extended Mount Plate.  By using this hole as the
alignment hole instead of the hole on the Load Beam, the HSA load
force is never degraded as shown in Fig. 2.
