I was thinking that the difference in CDRs and CDRWs is that once you burn something onto a CDR, that is it. There is no way to add to that CD. If you had a bunch of room left, it was my understanding that you lost that space on the disc.
Have I been misled?

I have a burner at work but not at home so I could do this if I could bring my camera and connector to work. Just want to make sure I know what CDs are best.
