And You Though 3D Was Mesmerizing, Wait Till 5D!
The invention of optical media is one of the most critical events in modern technology because in the amount of info that might be stored. Moreover, the discs themselves can last anyplace from twenty years to more than a person hundred, depending on the format (CD-R, DVD+R, etc.) and manufacturer. New technologies are being researched, on the other hand, that ought to soon supplant current formats – and two with the 3 most exciting ones involve the use of exotica like holograms and even biological material!
Referred to as HVD for Holographic Versatile Disc, this format has a demonstrated capacity of 5 terabytes. Sadly, the initial devices capable of playing them back are expected to cost tens of thousands of dollars, having a single disc running anyplace between just over a hundred to just under 3 hundred dollars.
Even additional intriguing, research 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 one particular disc! Data density on these protein-coated discs would be incredibly dense as such biological material is only a few nanometers wide.
Nevertheless, this study has been going on for almost half a decade now and no further news appears imminent; it looks likely that work is foundering on figuring out a procedure to address individual protein molecules for read/write purposes. Furthermore, a new method to focus the laser probably also requirements to become developed.
A a lot more right away promising technologies is the rather much more prosaic 5D-DVD, so named since with the five information layers involved. This technique seems capable of delivering ten terabytes of data, and due to the fact its encoding system is pretty similar to that currently in use, players for it really should also be backwards-compatible with today’s discs. 5D-DVD is hoped being commercially ready in about another five to ten years’ time.
