Here's an interesting thing. Our new backup procedure document says that
old tapes will be degaussed before being thrown away.
What's the best price you can find for a tape degauss machine? All the
devices I can find are priced at several thousand dollars. o_O

I picked one up years ago from Radio Shack for about $25. Try searching
for "bulk eraser", that may help.

Depends how erased you want the media. If the magnetic field isn't strong
enough, you can still recover data from it, even after it's supposedly been
erased. I saw a paper once where the government did a test to see just what
it took to *totally* wipe a HD, and the magnetic field needed to do so was
so strong that it physically warped the platters.

Why not shred and/or burn? Seems easier to me.

With the DDS tapes, what I do is open the case and cut the tape into
short lengths. (You can do this easily by cutting across the spindle.) I
don't know what the data rate is, but due to the compression you need
the parts of the tape in sequence for correct decompression. Good luck
arranging several thousand shards of tape back into the right order once
they've been messed up in the bottom of my bin! ;-)
I have *no idea* how you'd do that to an LTO tape though...

That *would* work if my shredder has a cross-cut. But it isn't, so the
tape would just come out the other end the same. (Possibly cut down the
middle.) It would probably tangle up quite nicely though, and probably
stretched and distorted well enough not to work...
