General Electric says its researchers have achieved a breakthrough in digital storage technology that will allow standard-size discs to hold the equivalent of 100 DVDs.First, the facts: the G.E. researchers’ work is in the field of holographic storage, an optical process that stores 3D images and digital data together, encoding it all and placing it on light-sensitive material such as a DVD. The theory is that holographic storage has the potential to pack data far more densely than conventional optical technology, such as what is used in conventional DVD and Blu-ray.
Holographic discs could hold 500 gigabytes of data. (In comparison, Blu-ray comes in 25-gigabyte and 50-gigabyte discs, and a standard DVD holds 5 up to about 8 gigabytes.)
