How to read ISO from CDROM?

Do I just read /dev/cdrom directly?

Seems to make sense. I want to verify my backup CD-RW disk is exactly equal to my .iso file that I burned to the disk. But I fear this will be very time consuming. Any better ways?

I am using a little script to run my backups like this:

#!/bin/bash
echo We are in the full.CD-RW.backup.script!

mkisofs -o ~/cd-rw/full.backup.iso -R -J -v -graft-points \
-path-list ~/backup.scripts/full.backup.dir.list

cdrecord dev=0,0,0 speed=32 blank=fast ~/cd-rw/full.backup.iso

echo Press Enter or close when done...

read REPLY

exit

cdchecksum=`dd if=/dev/cdrom bs=1024k | md5sum`
imgchecksum=`md5sum /path/to/iso`
if [ $cdchecksum != $imgchecksum ]; then
echo "Uhoh, images don't match"
fi

I use BackupPC. It's worked great for my network (60 workstations, windows & linux).
