Reattach a leader pin if it has become detached from the
magnetic tape and you must copy the cartridge's data onto another
cartridge.
Before you begin
The first meter of tape in an LTO tape cartridge is leader tape. Once the leader tape has
been removed there is a possibility of tape breakage. After reattaching
the leader pin, transfer data from the defective tape cartridge. Do not reuse the defective tape cartridge.
The Leader Pin
Reattachment Kit contains three parts:
Leader pin attach tool (see 1 in Figure 1).
A plastic brace that holds the cartridge door open.
Cartridge manual rewind tool (see 2 in Figure 1).
A device that fits into the cartridge's hub and lets you wind the
tape into and out of the cartridge.
Pin supplies (see 3 in Figure 1). Leader pins
and C-clips.
Attention:
Use only the IBM® Leader
Pin Reattachment Kit to reattach the leader pin to the tape. Other
methods of reattaching the pin will damage the tape, the drive, or
both.
Use this procedure on your tape cartridge only when the leader
pin detaches from the magnetic tape and you must copy the cartridge's
data onto another cartridge. Destroy the damaged cartridge after you
copy the data. This procedure may affect the performance of the leader
pin during threading and unloading operations.
Touch only the end of the tape. Touching the tape in an area other
than the end can damage the tape's surface or edges, which may interfere
with read or write reliability.

Procedure
To reattach
a leader pin by using the IBM Leader Pin Reattachment Kit, perform the following steps:
Attach the leader pin attach tool ( 1 in Figure 2)
to the cartridge 2 so that the tool's
hook 3 latches into the cartridge's door 4 . Pull the tool back to hold the door open, then
slide the tool onto the cartridge. Open the tool's pivot arm 5 .
Figure 2. Attaching the
leader pin attach tool to an LTO tape cartridge. To hold the cartridge door open, hook
the tool into the door and pull the tool back.
To find the end of the tape inside the cartridge, attach
the cartridge manual rewind tool ( 1 in Figure 3) to the cartridge's
hub 2 by fitting the tool's teeth between
the teeth of the hub. Turn the tool clockwise until you see the end
of the tape inside the cartridge. Then, slowly turn the rewind tool
counterclockwise to bring the tape edge toward the cartridge door 3 .
Continue to turn the rewind tool counterclockwise until
approximately 13 cm (5 in.) of tape hangs from the cartridge door.
If necessary, grasp the tape and pull gently to unwind it from the
cartridge.
Remove the rewind tool by pulling it away from the cartridge.
Set the tool and the cartridge aside.
Figure 3. Winding the tape out of the LTO tape cartridge. Turn the cartridge manual rewind
tool clockwise to see the end of the tape, then turn it counterclockwise
to bring the tape to the cartridge door.
On the leader pin ( 1 in Figure 4), locate the open side of the C-clip
2 . The C-clip is a small black part that secures the tape
3 to the pin.
Remove the C-clip from the leader pin by using
your fingers to push the clip away from the pin. Set the pin aside
and discard the clip.
Figure 4. Removing
the C-clip from the leader pin. Use your fingers to push
the C-clip from the leader pin.
Position the tape in the alignment groove of the leader
pin attach tool (see 1 in Figure 5).
Place a new C-clip into the retention groove 2 on the leader pin attachment tool and make sure
that the clip's open side faces up.
Place the leader pin (from step 6) into the cavity 3 of the leader pin attach tool.
Attention: To prevent the leader pin from rolling into the
cartridge, in this step, use care when folding the tape over the pin.
Fold the tape over the leader pin and hold it with your
fingers (see Figure 5).
Note: Use care to ensure that the tape is centered
over the leader pin. Failure to properly center the tape on the pin
will cause the repaired cartridge to fail. When the tape is properly
centered, a 0.25-mm (0.01-in.) gap exists on both sides of the pin.
Figure 5. Attaching the leader pin to the tape
Close the pivot arm 4 of the
leader pin attach tool by swinging it over the leader pin so that
the C-clip snaps onto the pin and the tape.
Swing the pivot arm open and trim the excess tape 5 so that it is flush with the reattached leader pin 6 .
Use your fingers to remove the leader pin from the cavity 3 in the leader pin attach tool.
Use the cartridge manual rewind tool to wind the tape back
into the cartridge (wind the tape clockwise). Ensure that the leader
pin is latched by the pin-retaining spring clips on each end of the
leader pin.
Remove the rewind tool.
Remove the leader pin attach tool by lifting its end up
and away from the cartridge.
