Not quite true, you don't actually have to make an ISO image. You can write
any file system type to a CD, it just happens that ISO is about the only one
anyone ever does. It's probably optimised in some ways for CD usage and it
also knows about tracks/sessions etc.
If you just want to store as much data as possible and don't care about
mounting it as a proper filesystem (a ghost image is probably a good
example) then you could do this
tar -zcf - |cdrecord [options] -
then later on
tar -zxf /dev/cdrom
to get the files back.
If the filesystem is small enough you can also do
cdrecord [options] /dev/hdaX
then later on
mount /dev/cdrom /mnt/weirdcd
