    Abstract: A storage medium can comprise a substrate, a reflective layer disposed on a side of the substrate, and data. The substrate can comprise a thermoplastic and a light-mark formed from at least a portion of light-marking additive mixed with the thermoplastic, wherein an optical property of the light-marking additive at an optical drive read wavelength can change due to being contacted with a mark wavelength. A method for using a storage medium can comprise directing a reading device to detect an inspection area of the storage medium, and wherein the inspection area on an authentic medium has a light-mark in a substrate of the storage medium that forms an optically induced signature. The optically induced signature can be converted to a digital identification signature and the digital identification signature can be verified for authenticity.
