Abstract

A new storage technique based on microscopic reflection holograms is presented. This technique has the potential to provide storage capacities of up to 100 Gbyte on a CD-like disk. The influence of wavelength- and angle multiplexing on the storage density is investigated and an estimation of the total storage capacity as a function of the focus radius is given. The major advantage of our holographic technique over other holographic storage approaches is the opportunity to achieve compatibility to existing CD and DVD systems.
