Digital holographic data storage prototype

Abstract

With the invention of new multiplexing and system techniques combined with a new type of storage material, Bell Labs has made significant strides towards establishing the commercial feasibility of holographic data storage. A density of 48.6 bits//spl mu/m/sup 2/ has been achieved in a photopolymer medium. Materials in hand will result in 5 1/4 inch disks with 125 GB of user capacity, >40 MB/s read rates, random access, and low cost removable media.
