Could you use a DVD burner to "draw" a QR code by burning it with the right pattern? What about write text?
I would guess a semi-destructive process affecting only the center layer but leaving the polycarbonate coating would be pretty durable.
Is it possible to "burn through" with a DVD burner?
see:

Special storage precautions are necessary to prevent LightScribe discs from fading. HP's LightScribe website warns users to "keep discs away from extreme heat, humidity and direct sunlight", "store them in a cool, dark place", "use polypropylene disc sleeves rather than PVC sleeves", and also notes that "residual chemicals on your fingers could cause discoloration of the label image". Such chemicals include common hand lotions and hair care products.
What shocks me is that people are putting these types of chemicals in their hair! Same thing as Coca Cola eats away at battery corrosion as well as refreshing your thirst!
