Abstract

Described is a one-piece plastic head/suspension shipping clip that is installed onto the actuator assembly following the attachment of the Head/Suspension Assemblies (HSAs) onto the actuator comb. This prevents the air bearing surfaces of the HSAs from contacting each other during shipping and handling of the actuator assembly which could cause damage and adversely affect the flying characteristics of the heads. The shipping clip is removed prior to the installation of the actuator assembly into the Direct Access Storage Device (DASD).

Head/Suspension Shipping Clip for Actuator Assembly

      Described is a one-piece plastic head/suspension shipping clip
that is installed onto the actuator assembly following the attachment
of the Head/Suspension Assemblies (HSAs) onto the actuator comb.
This
prevents the air bearing surfaces of the HSAs from contacting each
other
during shipping and handling of the actuator assembly which could
cause
damage and adversely affect the flying characteristics of the heads.
The
shipping clip is removed prior to the installation of the actuator
assembly into the Direct Access Storage Device (DASD).

      The clip, shown in the Figure, is positioned onto the actuator
assembly by first rotating it counter-clockwise approximately 30
degrees with respect to the actuator centerline.  This allows the
locating pin to pass through the swage bosses in the HSAs, the head
separators to pass by the outside of the HSAs and the locking feature
to pass pass through a core in the actuator comb simultaneously.
Once the clip has bottomed out on the actuator comb, it is then
rotated clockwise approximately 30 degrees until it is lined up with
the actuator centerline.  This positions the head separators between
the HSA's load beams and also engages the locking feature into the
outer arm.  Once in position, the clip is restrained from moving in a
direction parallel to the swage holes which could back-bend the
suspensions by the locking feature.  The clip is also restrained from
rotating...
