Tapes aren't hard drives. The very concept of "delete" and "free space" assumes the existence of some sort of filesystem to organize sectors, which tapes often don't bother with since they seek so slowly... Instead they'd be used as one big file, containing an archive like tar. There's exceptions, of course, but I can't tell if your tape's one of them from the precisely zero information given here. I'd guess that you'll need to deal with the program that created the tape data, not the tape itself.
