Istvan,

You may not be able to use tar to recover data from the tape.  It
depends on how the tapes were written.  If they were multiplexed with
multiple streams of data going to them tar generally cannot read this.
 If they were written as a single stream you most likely can recover
data from the tape(s) using the mt command and options as David has
pointed out.

I've had instances where one tape failed to read or write in one drive
but worked in another.  If you have additional drives free you may try
disabling the drive it failed on last time and let it try to read from
another drive.
