Abstract

A holographic optical disc stores digital information in the form of volume holograms. It utilizes the two dimensional surface of the disc as well as the Bragg selectivity of volume holograms to achieve three-dimensional data storage. Very high storage density, up to 100 bits/μm², has been demonstrated in the past in a thin disc-like medium. Here we focus on the data registration issues in the holographic disc system.
