If a tape is
used in the TK70 for writing - which means that the TK50 will
not be able to read the data - is it still possible to put the tape in a TK50
drive and start using it as a TK50 tape? Namely, does the TK50 drive
object to using a tape that has been written upon in a TK70 drive?
Once written by
a TK70 it stays that way until its bulk erased. I was told
that just inserting a blank tape into the drive would cause it to write a
"header" that identified it as a TKxx tape. This I don't know but I have
done the experiment you propose and the only way to get the TK50 to talk to
it was to bulk erase it.

Thank you. So I understand that a TK50 drive will not accept a tape that
a TK70 drive has actually used. But then, what happens after the TK50
drive has attempted to "use" that tape? Can the TK70 drive still actually
use the tape or must it be bulk erased again before either the TK50 or
the TK70 can actually "use" the tape? By "use", I mean at least try
an
INIT command - asuming that the drive thinks that the tape is online!
Sincerely yours,
