Abstract

Disclosed is a design for carriages used in Hard Disk Drives. This design employs a metal carriage and a coil which are bonded together by adhesive. The design described in this article has a protrusion or a recession in the bonding surface of the carriage. This unevenness will enhance the bonding in the shear direction.

Carriage Design for Coil Adhesion

      Disclosed is a design for carriages used in Hard Disk Drives.
This design employs a metal carriage and a coil which are bonded
together by adhesive.  The design described in this article has a
protrusion or a recession in the bonding surface of the carriage.
This unevenness will enhance the bonding in the shear direction.

      As shown in the Figure, the cross section of the material
enclosing the coil has a protrusion and therefore prevents simple
drop off in the shear direction.  Shear strength between the adhesive
and carriage is the weakest because coils are bonded with insulation
material after winding and this material has a very strong bonding
force with most adhesives.

      This bonding surface design can effectively improve the
adhesion quality, and it is applicable to carriages in a wide variety
of ranges.
