Science Fiction No More – Holograms Have Arrived

The invention of optical media is one of the most essential events in modern technology because on the amount of data that may be stored. Moreover, the discs themselves can last anywhere from twenty years to more than 1 hundred, depending on the format (CD-R, DVD+R, etc.) and manufacturer. New technologies are being researched, however, that need to soon supplant current formats – and two with the three most exciting ones involve the use of exotica like holograms and even biological material!

Known as HVD for Holographic Versatile Disc, this format has a demonstrated capacity of 5 terabytes. Regrettably, the 1st devices capable of playing them back are expected to price tens of thousands of dollars, with a single disc running anyplace between just over a hundred to just under 3 hundred dollars.

Even far more intriguing, investigation scientists are developing discs coated with light-sensitive protein made from a genetically altered microbe, in theory allowing up to fifty terabytes of storage on a person disc! Data density on these protein-coated discs would be incredibly dense as such biological material is only a few nanometers wide.

Nonetheless, this investigation has been going on for virtually half a decade now and no further news looks imminent; it appears likely that work is foundering on figuring out a method to address individual protein molecules for read/write purposes. Furthermore, a new way to focus the laser most likely also needs to be developed.

A more quickly promising technology is the rather a lot more prosaic 5D-DVD, so named simply because with the five data layers involved. This procedure appears capable of delivering ten terabytes of facts, and due to the fact its encoding system is very similar to that currently in use, players for it really should also be backwards-compatible with today’s discs. 5D-DVD is hoped to be commercially ready in about one more five to ten years’ time.
