I think the system handbook has a chart listing the tape compatabilities
across drives.  Or for each tape drive type, the tape formats it can
read & write.

Usually, as long as the physical tape/cartridge size doesn't change, a
tape drive can read & write 1 tape generation back and mostly read tapes
that are 2+ generations back.  Not always, though, as sometimes the
drive read/write heads changes to a sufficient degree that they cannot
read older tapes.
