Michael,

You can backup to disk, then move the backupset(s) to tape.  If you need to
restore however, you'll need to dump your tape back to disk.  There's no way
(that I know of) RMAN can  write or read to tape directly without a
third-party api that's linked through $ORACLE_HOME/lib/libobk.a

I'm fairly new to RMAN, and have been asked to look into the feasibility
of switching to RMAN for our backup strategy, with the goal of reducing
Legato licensing cost.  Now a tape-only strategy would be straight forward,
but we don't want to spring for the Networker Module for Oracle.  As would a
disk-only but we don't enough free disk space to keep more than one copy of
our 8-900Gb database online.

So is it possible to use RMAN to backup to disk, then move them to tape
without RMAN's involvement. and when a restore is necessary, use RMAN to
take the backup files directly from tape?  I'm willing to do a bunch of
research and testing here, but would rather not be banging my head against a
wall if this scenario is out of the question.  From other posts it sounds
like I'll have my work cut out for me at a minimum.  Thanks for your
thoughts on this matter.
