De-Swaging Mechanism

      Disclosed is a design for carriages used in Hard Disk Drives
(HDD) where a ramp is located near the Head Suspension Assembly (HSA)
to make de-swaging a simple rotating process.

      In HDD swaging is commonly used in attaching the HSA to a
carriage to create the Head Arm Assembly (HAA).  De-swaging is
necessary to replace defective heads.  In low profile HDD, the arms
are very thin, and the usual de-swaging method with a wedge inserted
between the HSA and the carriage is not feasible since this process
bends the arms.

      The Figure shows this new de-swaging process.  In this method,
a ramp is created on the arm as in the Figure.  A simple rotating
action de-swages the HSA from the arm.  No bending force is applied
to the arm.
