Question About Saving Documents to CD

I just bought a new iBook G4 with a Combo Drive. This is my first Mac and certainly my first computer without a floppy drive. When I asked about prices for an external floppy drive, the guy at the store said that I should try using just the CD drive first. He explained to me that using CD-RW's was just like using a floppy disk.

This is an example of what I want to be able to do:

Save DocumentA and B
At a later date, add DocumentC
Modify DocumentB and delete DocumentA
At a later date, create DocumentD and add it.

Can I do all this and still keep DocumentsC and D, and the modified DocumentB? Or do I basically have to erase the whole disk and overwrite all existing documents if I choose the add or modifya document at a later date.

I write many papers and the ability to add, delete, and modify documents is very important to me. I was not aware, before I bought the computer, that there was a difference between CD-RW drives and DVD-RW drives, other than the type of disk used.

I realize that I could just as easily save and do all that on the hard drive alone, but I rarely finish a whole document in one sitting and I want to be able to backup my work.

If anyone can explain to me what to do, I'd greatly appreciate it.

Get a USB thumbdrive. It's about the same price as an external floppy and holds a lot more. You can do what you want with a CD-RW, but for it to be actually usable, you have to buy Toast -a CD recording app.

EDIT: JOD8FY, he'll have to make sure not to close the session on the disk either (the little blue arrow on the "Burn Options" prompt).

You'll have to bear with me because I am a Windows to Mac convert.

Can you explain step-by-step, how to go about selecting the doc's I want to save, adding them to the CD window, and burning/keeping session open?
For the most part, I'll be saving word-processed documents.
