mkisofs is what you would use if the data was not already stored in iso
format.
If you wanted to create an exact duplicate of the original CD-RW, all
you need is
dd if=/dev/cdrom of=image.iso
Then use cdrecord to put it back later. (replace /dev/cdrom with whatever
device name you have for /cdrom in /etc/fstab).
Look at all the options to mkisofs and that will give you an idea of
all the things that could be different between the original and your
copy.
