Can some one tell me how an actual CDRW overwrites information?

My question is how does a CDRW overwrite information when saving data?
The scenario is that I use INCD (packet writing software) and have a simple batch file that will backup and overwrite data onto my preformated CDRW's.
Now someone has told me when using CDRW's it does not really overwrite. (which I'm starting to believe due to Nero's 2 options to Quick Erase and Full Erase CDRW's) This same guy told me CDRW's are not the best media to backup onto and that I should use HDDs. Well with data less than 800MB burnt daily to 7xCDRW's at $1-$2 each compared to multiple removable/portable $100 80GB Hdds the cost, portability and physical space is definately an issue.
I know that when you use a CDR you can multi session the disk and eventually max out the storage space, but on a CDRW, if you are overwriting the same file/folder on the CDRW, will it use the same storage space the CDRW has already assigned to that file/folder? Or will it take up a more space on a CD and wipe the previous data?
Can someone tell me how they really work when overwriting data onto CDRW's with and without INCD????
