$ ls -l /dev/st0*
crw-rw-rw-  1 root tape 9,  0 2004-09-18 07:51 /dev/st0
crw-rw-rw-  1 root tape 9, 96 2004-09-18 07:51 /dev/st0a
crw-rw-rw-  1 root tape 9, 32 2004-09-18 07:51 /dev/st0l
crw-rw-rw-  1 root tape 9, 64 2004-09-18 07:51 /dev/st0m

What differentiates st0 from a,l,m?
What does writing or reading to a tape using a,l,m signify?

I cannot seem to find any documentation clearly stating this.

Justin.
