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.
