I believe that beginning with SVR2.?, AT&T is pushing a new convention:
subdirectories in /dev for the names of secondary storage devices, i.e.,
/dev/dsk, /dev/rdsk, /dev/mt, and /dev/rmt for blocked and non-blocked
i/o on disks and magnetic tape, respectively.

For disks, the individual nodes look something like:
	/dev/dsk/c0d0s0		controller 0, drive 0, slice 0

I don't remember the individual names given to the tape devices, but why not:
	/dev/rmt/n1600		no-rewind-on-close, 1600bpi
