Labeling backup DVD+RW's

[Chris Jones <cjns1989@gmail.com>]

For my backups, I bought a DVD burner and a pack of DVD+RW's but I'm stuck
with one major issue. 

The upside of the DVD+RW's is kind of a yellow-gold-bronze color and I can't
seem to find any way I can write anything on them.

Does anyone know of a magical pen that would write something legible on that
surface and possibly come with an eraser so that I can reuse them and still
have a clue what I used them for?

Right now I have three labeled cases (current, minus one, minus two) for my
backups and I try to make sure I manually rotate the DVDs.

Is there an altogether better/smarter/reliabl-er solution?

Thanks!
