Process Cassettes for Plating Memory Disks

      Use of commercially available or specially made process
cassettes to hold thin film memory disks during plating operations is
disclosed.

      Use of commercially available (or specially made) memory disk
process cassettes in conjunction with a holding device are populated
with disks and used in a plating fixture which rotates the cassettes
and holding devices so as to insure plating integrity during the
plating operation.  An optional method of holding the disks would be
to mold a combination cassette/holding device.

      The figure illustrates the use of disk process cassettes 1 to
hold memory disks 4 while plating.  The populated cassettes 1 are
inserted into a specially fabricated arbor 3 and secured with a
suitable retaining device 2.  The arbor 3 is loaded into plating
fixtures 5 which rotate the arbor 3 while in the plating bath.  With
proper clearance around the outer diameter of the disk, as the arbor
3 rotates, the disks turn within the cassette 1, thus exposing the
entire disk surface to the plating bath.  As an optional
configuration, the cassettes 1 and the arbor 3 could be a one-piece
construction with an integral retaining device 2.
