Abstract

All types of hard disk drives share the same principal of having an actuator assembly (vertical or horizontal alike) with attached Head Suspension Assemblies (HSAs). HSAs are attached to the actuator's base, or comb by a swaging process. This process forms a permanent joint of two parts by piercing an oversized steel ball through these parts, thus expending one material within another.

HSA Magazine

       All types of hard disk drives share the same principal of
having an actuator assembly (vertical or horizontal alike) with
attached Head Suspension Assemblies (HSAs).  HSAs are attached to the
actuator's base, or comb by a swaging process.  This process forms a
permanent joint of two parts by piercing an oversized steel ball
through these parts, thus expending one material within another.

      The subject of the invention is a method of loading (or
merging) HSAs into the comb.  As described below, the magazine allows
for either manual or automated HSA merge operation.

      Fig. 1 shows the actuator assembly.  It consists of comb 1 and
HSAs 2 and 3.  The actuator has a total of twenty four HSAs: twelve
top HSAs 2 and twelve bottom HSAs 3.  The term top and bottom
describes a relative position of the read/write head in respect to
the disk drive.  A separator 4 prevents HSA heads 5 from touching
each other prior to installing the actuator into a disk drive.

      Fig. 2 depicts the top HSA.  It is made of a load beam 6
attached to a mounting plate 7 with its boss 8 and locating hole 9.
Head 5 and wire harness 10 are also attached to the load beam 6.  The
load beam is formed with a bend 11 for HSA function purpose.

      Fig. 3 shows a magazine which consists of base 12 with twelve
wave-shaped slots 13, and twelve HSA separator pins 14.  The base has
a set of four (two on each side of the base) locating holes 15 which
are...
