Abstract

Disclosed is a Disk Enclosure (DE) tape seal with regions free of adhesive for minimizing the adhesive exposure to the interior of the DE, and to provide a feature for starting the removal of the seal when DE rework is required.

Excluded Tape for Sealing of Disk Drives

      Disclosed is a Disk Enclosure (DE) tape seal with regions free
of adhesive for minimizing the adhesive exposure to the interior of
the DE, and to provide a feature for starting the removal of the seal
when DE rework is required.

      As shown in the Figure, the adhesive-free region along the
center of the tape is aligned with the opening between the base and
cover assemblies of the product when it is applied.  This minimizes
any direct or indirect exposure of the adhesive to the sensitive DE
components--actuator, disks, and heads.  A similar effect can be
achieved by "excluding" the adhesive in these regions by covering
with thin, inert material.

      A second adhesive-free (or excluded) region is present at the
end of the tape seal to provide a feature to attach to for easy
removal when DE reworks are required.  Adhesive is left on each side
of the removal feature to keep the end of the tape securely attached
to the DE during normal handling.

      Copper and aluminum are materials commonly selected for DE tape
seals.  However, this adhesive exclusion process is applicable to
tapes and seals made of all materials, including non-metals.
