I do not believe the tape is rewound before archiving, therefore it is possible to archive to a previously written tape, ie put a new arhive 'on the end' of an existing one. HOWEVER you would not be able to restore this new archive !! as the restore process does rewind the tape. It is not worth risking not being able to restore just for the sake of a few pounds for a new tape !!!

Before reading from or writing to a tape, the database server performs a series of checks that require the rewind." ontape doesn't rewind... it's worst ;) : It assumes is has been rewinded. Regards.
