Abstract

Disclosed is a simple device whose function is to reposition "Take-up Leaders" (TUL) in Digital Linear Tape drives. The need for this tool arises from the fact that the mechanical interface of the Digital Linear Tape cartridge with the Take-Up-Leader requires a very precise alignment of the Leader on the cartridge with the Take-up-Leader (TUL) within the drive. When these two elements do not align properly during cartridge insertion, the TUL becomes disengaged from it's Holding Arm and is wound onto the Take-up-Reel and further tape cartridge loading becomes impossible. The method/tool discussed here provides a simple device which is employed to reattach a TUL to the drive's Holding Arm, and therefore make it possible to load tape cartridges.

Method of Reattaching DLT(tm) Take-Up Leaders

   Disclosed is a simple device whose function is to
reposition "Take-up Leaders" (TUL) in Digital Linear Tape drives.
The need for this tool arises from the fact that the mechanical
interface of the Digital Linear Tape cartridge with the
Take-Up-Leader requires a very precise alignment of the Leader on
the cartridge with the Take-up-Leader (TUL) within the drive.  When
these two elements do not align properly during cartridge insertion,
the TUL becomes disengaged from it's Holding Arm and is wound onto
the Take-up-Reel and further tape cartridge loading becomes
impossible.  The method/tool discussed here provides a simple device
which is employed to reattach a TUL to the drive's Holding Arm, and
therefore make it possible to load tape cartridges.

   The solution/tool is described as a piece of flexible
plastic material shaped/designed and constructed such that it can be
inserted in-through the tape path of the Digital Linear Tape drives,
attaches to the TUL that had been rewound onto the take-up reel, and
pulls the TUL back through the tape path to the point where TUL is
reattached to the Holding Arm and released from the tool.  The tool
is constructed with nonabrasive, glide-inducing, non-head damaging
material (metal particle magnetic-tape) on one side for the entire
length.  This side of the tool is the 'outside'.  The front-end or
insertion-end of the tool has a looped nylon filament (leader),
oval-shaped and approx...
