CD-RW.  But observe some lines in my /dev/MAKEDEV:

case "$1" in
...
       sr)     echo scd ;;

...
for arg
do
        case $arg in
...
        sr|scd|scd-all)
                major=`Major sr 11` || continue
                for unit in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
                do
                        makedev scd$unit b $major $unit $cdrom
                        symlink sr$unit scd$unit
                done
                ;;
...
        scd[0-9]|scd[0-1][0-9])
                major=`Major sr 11` || continue
                unit=`suffix $arg scd`
                makedev scd$unit b $major $unit $cdrom
                ln -f scd$unit sr$unit
                ;;

This is the latest Debian woody.

Note the /usr/src/linux/Documentation/devices.txt (this is from the
devices.txt for 2.4.18):

    block       SCSI CD-ROM devices
                  0 = /dev/sr0          First SCSI CD-ROM
                  1 = /dev/sr1          Second SCSI CD-ROM
                    ...

                The prefix /dev/scd instead of /dev/sr has been used
                as well, and might make more sense.
...
It is recommended that these links exist on all systems:
...
/dev/scd?       sr?             hard            Alternate SCSI CD-ROM name


Note also this paragraph, from the same file:

For SCSI devices, /dev/tape and /dev/cdrom should point to the
``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
/dev/cdwriter and /dev/scanner should point to the appropriate generic
SCSI devices (/dev/sg*).

Dunno if that helps or not.
