scientists GE GE Global Research Center in New York today announced a breakthrough in data storage industry:
managed to successfully demonstrate in laboratory technology able to store 500 gigabytes on a single disc of low cost and the size of a traditional DVD. According to them, this amounts to 4 thousand times more information than a human brain can retain for the average person's life.
The new technique encodes the data in specific light patterns and subsequently stored on a light sensitive material forming microscopic holograms. These act as tiny mirrors refracting light patterns when the laser acts on them.
Holographic storage to store packet data in a much more dense on a particular surface that the conventional optical technology that DVDs found in common.
The advantage of this technique is that the system does not use a hard surface, but the entire volume. Some roasted as 3-dimensional storage which is used every corner of the disc.
The reading process is similar to that of current Blu-ray systems, but offers 20 times the storage capacity of a single-layer Blu-ray.
Currently there are several technologies that use holographic storage technology, but none has reached a stage done feasible to produce it in mass to be commercially feasible. GE's new technology promises to break the price barrier and produce a solution to achieve a commercial level.
