Holographic Memory 3D Storage By: Magen Price, Candice Fitzgerald, Ashley Jones, and Britney Breze
*Holographic memory is a technology that uses a three dimensional medium to store data • Data is stored in a clear, plastic, optical disk • The size of the disk is 130mm in diameter and 3.5mm thick • Holds 60x greater storage space than a standard DVD • The drive writes 10x faster than a standard drive • The disk can record up to 128hrs of video • The expected life of the disk is at least 50yrs.
How Does It Work?? * A data beam is crossed with a reference beam which produces an interference pattern. These patterns are recoded in light sensitive material. To retrieve data a reference beam is shone on that spot. Then the pattern and the reference beam recreates the original data beam. which is read by a digital-camera detector that translates the beam into a series of electrical signals.
Why is Holographic Storage Unique Compared to Today's Storage Mediums? * Holographic Storage Vs. Magnetic and micro electric Storage • Holographic storage last 50 years. • Holographic disc store data a page at a time on three dimensions. • Holographic disk do not rotate continuously. • Magnetic storage can last up to 10 years. • CDs and DVDs store info bit by bit on their surface. • CDs and DVDs rotate continuously.
Who are some of the people leading the research and production of the Holographic storage mediums? InPhase is 70 people startup company, that spun out of Bell Labs. InPhase's competitive edge lies in its partnerships with Hitachi Maxell, a leading producer of computer tapes and CD-ROMs, and--as of this May--Bayer Material Science, one of the world's largest makers of plastics used in optical discs.
Leading the Way Nelson Diaz--Chief executive of InPhase Demetrios Lignos -- InPhase's vice president of engineering Lisa Dhar —Leader of the Materials Team at Bell that produce a "two-chemistry" photosensitive polymer. Bill Wilson –Chief Scientist of InPhase. Kevin Curtis —Researchers and engineers, teamed up with Wilson.
How can Holographic storage be used? InPhase plans to go after high-definition digital video broadcasting and movie distribution for digital theaters: companies such as the Turner Broadcasting System want to archive videos. Larger scale, corporate and government data centers and hospitals could replace their huge storerooms of server racks and magnetic-tape reels with the quiet hum of holographic disc drives.
