Abstract: AN IMPROVED FREQUENCY SELECTIVE OPTICAL DATA STORAGE SYSTEM An optical data storage system that utilizes the frequency dimension to increase the storage capacity. The storage system has a storage material which contains a guest material such as cinnoline, which is dissolved in a host material such as naphthalene. This storage material system exhibits an inhomogeneous absorption line broadening and undergoes a photochemical reaction upon exposure to light.
