The simplest possible arrangement is to leave the device files unprotected,
and insist on using DOS format filesystem on them via mtools (there's a
version of mtools which reads a descriptor file rather than having the
floppy parameters canned in).
I use a pair of setuid wrappers to mount the cartridges and unmount them;
"mount_cartridge" turns into "mount -o nosuid,noexec,nodev /dev/sd4a /mnt"
and "unmount_cartridge" into "umount /dev/sd4a", but I'm effectively the only
user on my system, so the gaping security holes in this which I haven't
bothered to figure out yet are irrelevant...
