Web for Tape Drive Actuator

      Disclosed is a conductive web used in tape drives that
electrically shields the cables and provides a roll surface for the
cables.

      The head for Quarter-Inch Cartridge (QIC) tape drive actuators
has two flexcables, ofor the right and left modules.  These cables
must be electrically shielded from each other to minimize cross
talk.  Separating the cables with an electrically conductive web
shields the cables to minimized crosstalk.

      The latest QIC drives use a servo control.  The actuators for
these drives must allow the head flexcables to have a dynamic zone
for servoing.  A preferred cable geometry is a "U" shaped bend so
that the cables roll like in linear actuators.  For this case,
controlled surfaces must be provided for the cable to fasten to and
to roll on (on each side of the "U").  The web also provides a stable
roll surface for the flexcables which is a requirement for servoed
actuators.  Features can be put on the web to improve the adhesion
and help control the location of adhesive for attaching both the
cables to  the web and the leaf springs (which suspend the head) to
the web.

      Dynamic testing of the carriage assembly that holds the servoed
head is useful prior to attaching the head to create an actuator.  If
the web and leaf spring combination are attached to the carriage
assembly prior to attaching the head, then the entire carriage
assembly can be checked dynamically with a Transfer...
