Glad I read the article, this is fascinating:

> In 2012, a LightScribe optical drive was successfully used by Maher El-Kady, a graduate of UCLA, to turn a specially prepared graphite oxide layer coated onto a DVD into graphene.[10] El-Kady and Richard Kaner, his lab professor, used an unmodified LightScribe drive. The disc was prepared by coating the disc with an aqueous solution of graphite oxide and allowing it to dry. Areas of the coating illuminated by the LightScribe laser were turned into graphene. Various shapes can be drawn, which allowed the scientist duo essentially to laser-print an ultracapacitor on graphene using consumer-grade technology.

I have a LightScribe compatible external CD/DVD burner. It came with a LightScribe disc that I haven’t taken the plastic off still to this day. Since it only came with a single one I could never decide which one thing to use that one LightScribe disc for, back when I was still burning things on CD and DVD.

DiscT@2 (1), the granddaddy of them all.

This was followed up by Labelflash in 2007(2).

I was just thinking of those!

I had one of these as well... What a trip down memory lane, thanks for sharing.
