Holographic Data Storage
Introduction With its omnipresent computers, all connected via the Internet, the Information Age has led to an explosion of information available to users. The decreasing cost of storing data, and the increasing storage capacities of the same small device footprint, have been key enablers of this revolution. While current storage needs are being met, storage technologies must continue to improv...
متن کاملCompact Holographic Data Storage
Introduction: NASA’s future missions would require massive high-speed onboard data storage capability to Space Science missions. For Space Science, such as the Europa Lander mission, the onboard data storage requirements would be focused on maximizing the spacecraft’s ability to survive fault conditions (i.e. no loss in stored science data when spacecraft enters the “safe mode”) and autonomousl...
متن کاملLiquid crystals for holographic optical data storage.
A tutorial review is presented to inform and inspire the reader to develop and integrate strong scientific links between liquid crystals and holographic data storage, from a materials scientist's viewpoint. The principle of holographic data storage as a means of providing a solution to the information storage demands of the 21st century is detailed. Holography is a small subset of the much larg...
متن کامل1 Holographic Optical Data Storage
Although the basic idea may be traced back to the earlier X-ray diffraction studies of Sir W. L. Bragg, the holographic method as we know it was invented by D. Gabor in 1948 as a two-step lensless imaging technique to enhance the resolution of electron microscopy, for which he received the 1971 Nobel Prize in physics. The distinctive feature of holography is the recording of the object phase va...
متن کاملOptimizing the holographic digital data storage channel
Holographic storage has the potential to become a digital data storage technology with fast readout and high density. Computer users have come to expect, however, that data retrieved from their storage devices will be retrieved error-free (with a probability of error <10−12). In both conventional storage devices and holographic data storage, achieving this degree of reliability involves a good ...
