Given that IBM has reported a way to create multi-terabyte tapes (and presumably read them), I find it hard to believe tape is dead. Whether there will be enough drives of a given type commonly available at the dwindling number of mainframe sites to make it worth while for IBM to have that tape drive to create the tapes is another question. 3420s and then 3480s were at one time ubiquitous. Now I suspect the variety of incompatible drives is making make it increasing interesting for any vendor to supply their software on tape.
