Method to Attach Head/Suspension Assemblies Centrally to Actuator Arms

      Disclosed is a technique for attaching back-to-back magnetic
recording Head/Suspension Assemblies (HSA) centrally to arms of an
actuator to accommodate very closely spaced magnetic data disks.

      Fig. 1 shows a pair of back-to-back head/suspension assemblies
(1) attached together near the rear or base of individual load beams
to
form a "wishbone" style assembly.  This arrangement places
back-to-back
assemblies as closely together as practical for any given head height
and gimble design.  Several techniques for attaching such an assembly
centrally to an arm (2) or arms of a disk file actuator are
illustrated
in Figs. 2, 3 and 4.  In each case, a slot is provided centrally in
the
end of an arm and parallel to the surface of each data disk.  The
height and depth of the slot is sufficient to fit the base of a pair
of
back-to-back head/suspension assemblies.

      A first method of head/suspension to arm attachment is
illustrated in Fig. 2.  A punch (3) and die (4) cooperate to form a
depression in an arm.  The depression mates and interlocks with a
hole provided in the base of a head/disk assembly (HDA) pair and,
therefore, firmly attaches an HSA to an arm.

      A second method of HSA attachment is illustrated in Fig. 3.  A
pair of spot welding electrodes (5) cooperate to form depressions
from both sides of an arm.  These depressions pass through a hole
provided in the ba...
