Depending on the media and whether or not you want to be able to
re-use the media in the future.  You can get a Bulk Eraser, which is
just a device which projects a strong magnetic field.  This works for
DLT tapes, but not for LTO (and some others!) because they LTO tapes
depend on the factory written servo track on the media.

If you don't care about the tape afterwards, any tape can be bulk
erased.

You'll have to do this will some tapes if you want to re-use them.
