Thanks Paul, I still have a question.
If I have new tape (or old but unused tape), should it need to be formated first or just erase/overwrite is suficient? Is there any standard file format for tape drive?
I'm not sure. I think in most cases you can just erase or overwrite it but some tape technologies may require formatting first.
Try it and see, e.g. archive your home directory:
$ cd ~ $ tar cvf /dev/st0 .
Then see what's on the tape:
$ tar tvf /dev/st0
