Figure 1-4. Media Inspection - Bad Tape
Figure 1-5 displays a tape that has been dropped and the cartridge seam has
split.
NOTE:
Newer versions of LTO tapes have plastic-welded seams to prevent
splitting; however, the tapes must be checked for leader pins that may have
dropped inside the cassette housing.
