I see two possibilites:

1) Tell tar to create a multi-volume archive using the -M and -T option
(see manpage). Multi-volume archives cannot be compressed, however,

2) Create one big compressed tar file and then use split (see "man split")
to cut it into pieces. Then burn these onto your CDs.

Hope that helps
