Just read it, or copy the entire CD to /dev/null and see if there are any
read errors reported.

Most can. Some *only* do that!

If you make the RT-11 part as some sort of container file (LD: volume?),
you can use mkisofs to build an image consisting of everything else, and
work out its size. Then burn a CD which has two (or more) tracks: first
the ISO-9660 part (possibly with Rock Ridge and/or Joliet extensions), then
the container (or put some padding between to make the start of the
container where you want). Or start with the container, though I'm not
sure if that necessarily means it would start at a specific block. I'm
also not sure how many systems can read a multi-track data CD.
The way people usually do it for EFS disks for IRIX (EFS is the native
SGI/IRIX filesystem format used for bootable installation CDs) which have
to have partitions, is to build the image on a hard drive first, and burn a
raw copy of the entire hard drive (rather than the files/filesystem on it).
