TECHNICAL ABSTRACT (LIMIT 200 WORDS)
Enormous data capacities and high read/write rates make optical holographic data stor-age (HDS) systems the most promising approach for next-generation computer mass-storage solutions. Recent breakthroughs in holographic recording media have dramatically accelerated the development of commercial HDS products, and have shifted the development focus to opti-mization of HDS optical systems and components. We propose here the development of an optimized HDS write-head component comprising a spatial light modulator (SLM) with inte-grated optical phase mask. This integrates essential optical beam conditioning functions into the write-head to eliminate recording-plane ?hot spots? that otherwise saturate the recording media, reducing capacity and fidelity. Our integrated approach uniquely accomplishes this without increasing HDS system cost or complexity. The use of innovative micro-optics tech-niques to fabricate the phase mask will allow SLM production to remain compatible with proven liquid-crystal-on-silicon (LCOS) microdisplay mass-production processes, ensuring write-head manufacturability. Development of this optimized write-head component will enable compact, inexpensive HDS drives offering storage capacities from 100 GB to over 1 TB and read/write rates in excess of 1 Gb/s on removable, archival media. Such drives will have widespread application, initially in professional digital video recording and in enterprise archive and backup networks, and eventually in personal computing.

POTENTIAL COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
Initial holographic data storage products are expected to offer removable-media, WORM (write once read many times) functionality, and are targeted for enterprise and professional applications. Ongoing cost and performance improvements should result in products with rewrite capability and costs low enough to hit consumer and personal computing markets. Market segments for initial products where these attributes are important include: 1) professional digital video recording and digital-cinema content distribution, 2) general-purpose enterprise data archives and backup, and 3) medical image acquisition and storage.

POTENTIAL NASA APPLICATIONS (LIMIT 150 WORDS)
Initial HDS products are expected to offer removable-media, WORM (write once read many times) functionality, and are targeted for enterprise and professional applications. Ongoing cost and performance improvements should result in products with rewrite capability and costs low enough to hit consumer and personal computing markets. Of special importance to NASA, these products will be valuable for earth-sciences and geophysics data acquisition, processing, and storage.
