The promise of using volume holography to deliver high performance optical storage systems is at hand. The
possibility of extremely large storage capacities and fast transfer rates make holographic storage ideal for high
performance video applications. An overview of advances at InPhase Technologies toward the first drive product is
presented. InPhase Technologies is developing a holographic recordable optical drive and associated disk media for
professional archive applications. The target user capacity for the first product is 300GB of user data with sustained
write and read user transfer rates of 20MByte/s. The architecture, design and implementation of the holographic
drive are described here.
The promise of using volume holography to deliver high performance optical storage systems is at hand. The possibility of extremely large storage capacities and fast transfer rates make holographic storage ideal for high performance video applications. An overview of advances at InPhase Technologies is presented. Progress toward high-density implementations as well as the development of a functional prototype is presented. These systems are the first fully functional holographic recordable drives developed. Their development paves the way for the commercialization of this technology.
An overview of the InPhase Technologies holographic demonstration platform is reviewed and a new holographic multiplexing technique presented. The platform is a compact, mobile system and the first fully functional, portable; holographic recordable drive complete with custom optics and control and channel electronics. In addition a description of "POLYTOPIC MULTIPLEXING" is presented. This innovation allows us to simplify the system geometry and optimize the media usage enabling a sustainable product road map. These developments pave the way for the commercialization of this technology.

We report new photopolymer media for holographic data storage (HDS) at blue wavelengths (~ 405 nm), which show great promise for a practical HDS system.
An easily fabricated organic holographic media is presented that is rewriteable, sensitive to 407nm light, and that exhibits high storage capacity, sensitivity, and environmental robustness.

Holographic data storage (HDS), which makes use of the full volume of the recording medium, possesses high potential by promising fast transfer rates of hundreds of Megabytes/sec and storage densities greater than 200 Gbytes per 120mm disk. The restrictions that are placed on the holographic media, however, are stringent. Described here is a high performance photopolymer based medium that has the properties necessary to enable this technology. Through the use of several different holographic techniques, the material characteristics that are necessary for holographic storage products may be determined. The two different systems that are discussed here include Plane Wave and Digital Holographic Data Storage. These measured characteristics include high dynamic range (M/#), sensitivity, and small recording-induced Bragg detuning. In addition, results of archival and shelf-life environmental testing of the media will be discussed.
