Cygwin works device magic via the registry mount table. Once you have
done the mount, any reference to the device name, e.g. /dev/st0, is
directed to the tape device that you mounted. The mount only has to be
done once and you may thereafter refer to the device. The choice of name
for the device is up to you. For example one of my machines has two tape
drives and they are mounted as

mount -f -s -b "//./tape0" "/dev/st0"
mount -f -s -b "//./tape0" "/dev/nst0"
mount -f -s -b "//./tape1" "/dev/nrmt0"
mount -f -s -b "//./tape1" "/dev/rmt0"
