storage technology has so far had a successful development after he threw away the ugly diskettes and embrace the CD, now we also plays throwing it away because we have several alternatives from which we can cite the famous USB Keys are reaching up to 64 GB, Blu-Ray and for those who still do not have a Blu-Ray device the DVD of 4.7 GB to 9 GB, it seems that now any need for storage that we have before it a solution and not any new technology is imperative, in this order, the story takes care to remind us that it is not , that you see today's technologies to their maximum expression in terms of speed and storage will require new technologies to improve existing today, which makes us wonder what comes after Blu-Ray ?
Holography
Holography
Discs know CD, DVD, HD-DVD and also the Blu -Ray contain the information in a linear fashion, made through a single optical beam, this means that each point on the disc just be a bit of information osea yes or no value, the difference using the holography is that it can record up to 60,000 bits of information in a single light pulse because instead of taxing a value that can be whether or not what is recorded is a holographic image, t period suggests that the holography will have much to do with the storage units of the future and the successor to the blu-ray is called Holographic Versatile Disc ( Holographic Versatile Disc, HVD ).
The HVD
The capacity can be about the HVD is 3.9 terabytes (TB) or 3.993 GB, I mean 80 times the capacity of a blu-ray disc or what is the same 820 DVD-quality movies, others that get you calculate the amount of information we put in a HVD that I leave to the imagination of everyone because it depends on the type of content that we got used store, so if it'll be a great relief to system administrators because it removed an enormous workload to stop working with cartridges 250 GB tapes is not the same as a tape cartridge a beautiful album of the same size as a DVD.
HVD speed
Contrary to what happens in the field of optical devices is the speed above the strongest point of HVD with a transfer rate of 1 gigabit per second on average, or what is the same as an HVD disc could transfer data at twice the speed that modern hard drives.
can conclude that the CD, DVD, Blu-Ray, HD-DVD is a family of optical discs have their days are numbered because they use a technology can no longer reach perfection even more than what has come to be Blu-Ray so this technology will give way to the new technology of HVD discs.
