ABSTRACT:
A method for selectively marking a surface of an optical disk includes providing an optical disk, wherein the optical disk includes a metal, an electrolyte disposed on the metal, and a photoconductor disposed on the electrolyte, applying a voltage to the optical disk, the voltage being associated with a desired anodization color, and selectively applying a laser to the photoconductor to initiate anodization of the metal.
