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. The storage capacity and interchannel crosstalk are analysed as functions of data-channel wavelength separation and reading beam spot size. A storage capacity of 9.7 Gbyte per disc is provided when six layers and six wavelengths are used
