Abstract

An optical disc for data storage includes a layer of color-shifting material. Light passing through the color-shifting layer will have a color determined by the various constructive and destructive interference of the various wavelengths after they have passed through the material, diffracted while passing through the material, and are reflected off of various portions of the material, resulting in a color change when the viewing angle is changed. Additionally, an optical variable device may be defined within the disc, and may include the color-shifting layer.
