Structurally stable optical data storage medium |
摘要 |
An improved optical data storage medium and a method of forming and utilizing such a medium. One such optical data storage medium has a substrate having an upper surface including a series of physical deformations which encode data. A reflective film stack carried by the upper surface of the substrate includes both a reflective layer and an overlayer. The reflective layer is formed of a reflective metal and is able to generate a readable data stream from a reflected data reading light. The overlayer is formed of a material which has a higher Young's modulus and/or a higher modulus of compression than the reflective metal and is less reflective of the reading light than is the reflective metal at the same thickness. A protective layer is carried behind the reflective film stack and may serve to protect the reflective film stack against physical damage and environmental attack.
