As reports Associate, general electric company was able to develop the holographic disks technology which can store a tera-byte of data, in this case, it will be possible to store this information will be with the aid of several finished drive blu-ray. Holographic exists already about 30 years, but there was no possibility to derive it on the mass market due to some complexities. The complexity of production was the basic reason. In particular, holographic disk must satisfy strict criteria, including: the extended dynamic range, high photosensitivity, shrink resistance, optical transmission, thermo- and hydrostability, and to also have low price. For scientists from General electric, it was possible to go around these problems, after selecting the necessary disk. Holographic disks technologically are not too complex. Laser beam is divided into two threads.  Moreover, the upper  data layer can be read now with usual Blu-ray drives, and in order to count all layers, some modifications of this reading device are necessary. The reading speed of holographic disks  is approximately 5 times higher than DVD speed , and the access time is reduced in all to 3 milliseconds. Mass market is expected in 2-3 years. Holographic disks are completely reliable, they will have a high index of speed and volumes; Related Products :
