It is, indeed, possible to have multiple sessions on a CD-R. I've done it.
It is also usual to import the previous session. If you don't, Windows
appears not to be able to "see" the previous data. Note, however, that
AmigaOS *can*.
I've done this personally. Burn several sessions to a CD, and when you
insert it, AmigaOS prompts you for which session you want to access.
(Recall that AmigaOS tracks all disk insert/eject events.) You then see
the data in the selected session only (and any data it imports).
My Amiga was using a plain ordinary IDE CD-RW drive, so it seems to me
that a PC should be able to do the same trick, given the correct
software. It wouldn't surprise me if something like cdparanoia can grab
an arbitrary session, dump it into an ISO file, and then let you
loop-mount that to read it...
