Head Suspension Assembly Magazine

       A fixture or magazine for holding magnetic head
suspension assemblies (HSAs) during assembly of a direct access
storage device (DASD) actuator is disclosed.  The magazine will hold
and locate the head suspension devices so that they can be inserted
into the actuator body or base during an automated assembly process.

      A head suspension assembly shown in Fig. 2 is placed in the
magazine shown in Fig. 3.  The head suspension assembly is placed in
the magazine by bringing the mount plate 9 in contact with the
locator 16 of the magazine such that the boss 10 rests on radius 21.
At the same time, spring-loaded lever 22 must be pulled back out of
the way and the load beam 8 must be placed against pin 15 so that
the suspension is straight.

      The Z direction or height of the suspension is fixed by pushing
the mount plate 9 down until the mount plate edge 19 comes to rest on
step 20 of locator 16.

      The X direction is fixed when lever 22 is released and the
spring pressure pushes on the back of the mount plate to push the
front edge against the locator hook 23.

      The suspension is held firmly in place by the hook 23 on
locator 16 and tab 22 on lever 17.  The head 7 is held in the
correct position when the load beam 8 rests on pin 15.

      When all the head suspension assemblies are loaded into the
magazine (Fig. 4) the locators 16 hold them in relative position to
each other so that they all c...
