Abstract

We have achieved a surface density of 10 bits/micrometer² (6.5 Gbits/in²) with an experimental holographic storage setup, using DuPont's 100 micrometer thick photopolymer as the recording medium. Its performance characteristics in terms of access rate and signal-to- noise-ratio are described. Furthermore, a simple holographic 3D disk system with high surface density (10 bits/micrometer² using a 100 micrometer thick recording material) and an architecture similar to compact disks is shown.
