Using tar onto acd may not work, but utilizing atapicam, it could
eventually work with cd directly:

	% tar cvjf /dev/cd0 ~/.* ~/devel ~/music ~/texts

But this does not (!) make the media mountable! You may see that
as a disadvantage, but maybe it's not: You can access it now
directly without needing to mount it, and you can extract from
it by selection, e. g.

	% tar xvjf /dev/cd0 ~/music

to only extract the music/ subtree.

The tar "file system" is best for interoperability because (if
I may say this) every UNIX-like OS can read tar, no matter if you
put it n discs, disks, tapes or even hard disks or USB sticks.
