write-once filesystems for tape?

[max at spam.uchicago.edu]

Actually, I don't need a full-blown file system; I'd settle for operations 
enough for me to make and delete directories and add and delete files.  I'd
even settle for a good tape archive program.

tar(1) would just about do if I could get the "r" option to work.  I have a 
sun 4/110 with an exabyte drive (I really want to store hundreds of Meg on 
this thing), and the "r" option doesn't work.

Does anyone have any suggestion or pointers?  Thanks,
