Well, it also has a table of contentswhichis what allows you to skip to
the beginning of the next track, or skip to sub areas within one track.
Ie, it is a filesystem of sorts, but it is not iso. (well there probably
is some iso number for the layout of music on a cd, but it is not the
same as iso9660)

Thats just what I don't want to do. I want, by the look of it, a "raw
disk image" backed up so I can spawn new disks as required, but I don't
want a collection of "loose" tracks.

I'm wondering if I could simply rip a finished CDROM with DD to generate
that single disk image? More reading to do.

Thanks for not decending into being patronising there. ;\

Its looking as if I've set myself a "mission" here. :|
