Abstract : In this final report, results from several different high density holograph data storage experiments are presented to demonstrate that information can be stored more densely using holography We start with a preliminary experiment to show that the DuPont photopolymer could indeed be used to record high density holograms with sufficient SNR and end with an experiment where a surface density of 100 bits/micron2 was achieved. For one of the high density experiments we constructed a functional holographic 3-D disk record/read station. A new multiplexing method called 'shift' multiplexing was used to write overlapping holograms in a spiral track on the disk, just like the compact disc format. The capacity of a 120 mm disk with a surface density of 100 bits/micron be around 100 Gbytes, roughly 100 times more than the current compact disc. We end the final technical report with some suggestions for future experiments in the area of holographic 3-D disks.
