Multilayer optical storage is a viable means of increasing the capacity growth rate for optical storage. Two-photon materials and systems as a means to provide monolithic production of hundreds of data layers within inexpensive plastic disk media were explored. Two-photon photochromic disk and cube media and parallel access reading and writing systems were developed, with the goal of simultaneously providing more than 100 GB capacities and data transfer rates exceeding 1 Gb/s. This approach relies on recording bits in a volume by using two-photon absorption. The results indicate low crosstalk between layers and excellent stability of the written bits at room temperature.
