Address Book Data File???

[ShMac]

Until I have the cash for a HD enclosure, I am backing up weekly
on CDs since I already own a stack.

Is there a data file for the Apple Address Book program I can add
to my weekly Toastings?

The location of such a file depends on what operating system you're running... I find it easiest to use Address Book's own backup feature from the File menu. Then you can revert to this backup from within Address Book if necessary. The same function is in iCal.
