摘要： An optical recording medium includes a light-receiving surface that receives incident light and at least three information signal layers on which information signals are to be optically recorded. Among the at least three information signal layers, the information signal layer closest to the light-receiving surface has a reflectance in a range of 4% to 11%.

摘要： An optical device, such as an optical storage medium, comprises a layer of material in the solid state that has a refractive index that is switchable between at least two stable values by applied light. A reflector is spaced apart from the layer of material by a solid spacer layer transmissive to light.

摘要： A holographic storage layer includes a reflective structure and photosensitive units. The reflective structure is a grid-shaped structure and includes cavities. The photosensitive units are disposed in the cavities, in which each of the photosensitive units is surrounded by the reflective structure. First openings and second openings are defined by the reflective structure, and the photosensitive units are exposed by the first openings and the second openings respectively.
