Wire and Snare-Tube Guide on Head-Arm by

Mount

Plate

      Disclosed is a Suspension Mount Plate Design used in Hard Disk
Drives.

      Generally, Hard Disk Drive (HDD) became data capacity bigger,
and physical size smaller, day by day.  A small HDD needs small
parts: Head Actuator Assembly (HAA), Disks, Spindle Motor, etc.; that
is to say, small Head Gimbal Assembly (HGA), Suspension, Snare-Tube
were needed in current HDD.

      So, in this situation, Snare-Tube is different from other metal
parts because of its softness.  It is difficult to control Snare-Tube
position in narrow space between disks, for avoiding a contact
between Tube and disk surface.

      This disclosure shows how to control tube position with Mount
Plate design.  The following figures show examples of this method.
Fig. 1 shows a Guide with part of Mount Plate side.  Fig. 2 shows a
Guide with whole side of Mount Plate.  Fig. 3 shows Extension of
Mount Plate to form a Guide.  Fig. 4 shows Bending the tip of a Guide
in order to keep Head tubes.

      The advantages of this method are the easiness in building
process and exactness of TUBE (and wires) location.
