Abstract
A system is proposed that combines both the multilayer storage and the wavelength multiplexing afforded by using volume holograms to enhance by several fold the optical data storage capacity of compact discs. T he storage capacity and interchannel crosstalk are analysed as functio ns of data-channel wavelength separation and reading beam spot size. A storage capacity of 9.7 Gbyte per disc is provided when six layers an d six wavelengths are used.
