发明名称 Optical storage device with print layer surface feature
摘要 An optical storage medium having an optically-transparent flexible substrate, a reflective layer bonded to the substrate surface, and a print layer bonded to the reflective layer, where the print layer also includes a modified print layer region such as a lenticular region, a diffractive optical element, an embossed region, a holographic image, a magnetostrictive ferromagnetic material electronic article surveillance tag, or a radio-frequency surveillance tag. The layers are individually formed and laminated together, the laminated combination subsequently cut into a plurality of discs.
