I try many times to append on a tape.
In this way i use the device "/dev/[r]mt/0n" wich must invoque the driver
with the "no rewind on close" option.

SO:
  -Successives writes (from the begining of the media) works fine if no other
operation on the tape occurs between them.

  - successive read works but often need two retry between each iteration.

BUT:
To append on an already written tape one need:
  -rewind it.
  -forward skip files already there (with "mt fsf x", or reading them).
  -then write the new file.
This don't work (error: can't write output. etc...). I try many sequences
without success.

If someone could help...
