The lines below are the contents of CD-Writing HOWTO. Give it a try.
shell> IMG_SIZE=`mkisofs -R -q -print-size private_collection/ 2>&1 \
| sed -e "s/.* = //"`
shell> echo $IMG_SIZE
shell> [ "0$IMG_SIZE" -ne 0 ] && mkisofs -r private_collection/ \
|cdrecord speed=2 dev=0,6,0
tsize=${IMG_SIZE}s -data -
# don't forget the s --^ ^-- read data from STDIN
The first command is an empty run to determine the size of the image
(you need the mkisofs from the cdrecord distribution for this to
work). Maybe your writer does not need to know the size of the image
to be written, so you can leave this dry run out. The printed size
must be passed as a tsize-parameter to cdrecord (it is stored in the
environment variable IMG_SIZE). The second command is a sequence of
mkisofs and cdrecord, coupled via a pipe.
