Holographic Memory (Next Generation of Storage)
Imagine being able to record 100 movies on a disk the size of a CD – - or one day recording the contents of the Library of Congress on such a disk. These are the promises of holographic data storage.
Holography enables storage densities that can far surpass the super paramagnetic and diffraction limits of traditional magnetic and optical recording. Holography can break through these density limits because it goes beyond the two-dimensional approaches of conventional storage technologies to write data in three dimensions. In addition, unlike conventional technologies which record data bit by bit, holography allows million bits of data to be written and read out in single flashes of light, enabling data transfer rates as high as a billion bits per second (fast enough to transfer a DVD movie in about 30 seconds). Holography stacks information throughout the thickness of a storage medium, instead of just writing it to the surface.
With its powerful combination of high storage densities and rapid data transfer rates, holography stands poised to become a compelling choice for next-generation storage needs. Days are not far, isn’t it?
