Three-dimensional multi-layered optical storage is one of the most promising methods that break the limitation of recording density in optical storage. It stores the bit information onto the multilayered recording planes inside the thick recording medium and realizes the tremendous large recording capacity. This paper describes the recording/reading principles, the systems, and the materials suitable for three-dimensional multi-layered memory. We also present the experimental results that using photochromic organic materials and rhodamine-B-doped and Au(III)-doped PMMA for recording medium.
