New Disc From GE, 100 DVDs in a Disc!

General Electric (GE) has made a success breakthrough in digital saving technology. They made a standard disc which can hold equal with 100 DVDs. Wow, sounds very incredible! We don’t need to keep 100 DVDs instead of 1 is the same. But, we can not get too excited now since it is only success in laboratory stage and not ready to be mass produced for consumer level.

Industry analysts and optical storage experts said GE’s breakthrough in digital storage has been a big step forward and will gain a wide range of potential uses in commercial, consumer markets and scientific.

The invention of GE related with holographic storage. Holography is an optical process that stores not only three-dimensional images like the ones placed on many credit cards for security purposes, but the 1’s and 0’s of digital data as well. The data is encoded in light patterns and stored in a light-sensitive material. The holograms act like microscopic mirrors that refract light patterns when a laser shines on them, and so each hologram’s recorded data can then be retrieved and deciphered.

The potential of holographic technology has long been known. The first research papers were published in the early 1960s. Holographic storage has the potential to pack data far more densely than conventional optical technology, used in DVDs and the newer, high-capacity Blu-ray discs, in which information is stored as a pattern of marks across the surface of a disc.
