storing thousands of megabytes of data three-dimensionally

Besides more rapid access quickness, holotechnology data storage and analytic structures also enable significantly more storage capacity than two-dimensional systems. With two-dimensional media, only the surface is employed to store data. While blue laser and nanotechnology are making possible improvements in data density, the needs of expected uses may exceed the constraints of two- dimensional magnetic and optical information storage density. Holographic information storage and processing "break the surface barrier" because various pages of information are recorded three-dimensionally in overlapping slices throughout the depth of the recordable media. Thousands of hologram data pages may be saved in a single holodisk or holographic cube. Alternative page are recorded and retrieved using reference rays with various projection angles or wave phases. Data storage capacity for 3D holotechnology systems is orders of magnitude more than that of two-dimensional systems. The Heliodisplay for additional holotech info.

Over the next several years, many experts expect exponential growth in data storage requirements. Three-dimensional volumetric holographic storage applied science is likely to play a large role in serving this increasing need. Holotech information storage breaks the surface barrier by encoding information permeating the thickness of optically sensitive media. Holotech information storage occurs a whole, megabit page at a time in three dimensions. This makes it possible for large jumps in both information storage density and access speed. First generation uses of high-cost, early-generation holographic information storage media are mainly for top-of-the-line archiving in large information centers, banks, and medical centers where it is important to rapidly access massive amounts of data. Holographic disks enable faster access than magnetic tape. There is also some early evidence that holotechnology disks can preserve data integrity up to five times longer than magnetic tape.
