The International Hologram Manufacturers Association has reported on the development of new hologram technology ‘hVault’ by InPhase.
Many of us have never thought about where all the videos on YouTube are stored, or where Amazon stores all the details of its product offerings. Currently, they’re all stored on high-powered electronic servers, which use magnetic storage devices.
This may all change with the introduction of holographic storage systems, which consumes just one per cent of the power of equivalent magnetic disk storage.
Servers holding cloud data have become so big that they are now being located close to hydroelectric installations to reduce the energy costs associated with cooling them. However holographic storage systems can operate without any special power conditioning or cooling.
This image shows the holographic recording process. A laser beam is divided into a reference beam and an object beam. The object beam is programmed with data from a digital display.
This image shows the reference beam reconstructing an image of the recorded data and projecting it onto a screen. By changing the reference angle, several images can be recorded in the same space making efficient use of the material.
Expected to undergo site testing towards the end of 2012, with delivery of fully operational systems expected in the first half of 2013, the key to the new system will be the archival storage property of the holographic medium, which could potentially be in excess of 50 years.
