Homebrew PCBs

I never thought about the tracking and that the drive might reject it
knowing it is not a CD.

I was a cute idea even if not practical at all ......

I assume just like a writable CD, the lightscribe part also needs a pre-made
spiral groove in the material for the laser to follow.

If this is not there I expect the drive will just say "no disc" and do
nothing.

on a CD. "Write" the picture to the "CD" and hopefully it will vaporize the
paint. Afterwards etch the boards as usual.
