Holographic discs give optical storage technology an upshot
We’ve heard of DVDs, we’ve heard of Blu-ray, and as the relentless technology keeps evolving, we now hear of a holographic disc that is rightly being touted as the future of storage discs. Developed by General Electric Global Research team, the Holographic disc can store data worth a 100 DVDs or 20 Blu-ray discs in a single casing.
This heightened level of data density in the disc has been achieved with the use of microscopic holographic patterns in light sensitive plastic. Data on these discs can be stored in a 3D format, and these discs use the entire volume to store the data, unlike conventional ones that just use the surface. Discs that can hold 500 gigabytes of information, these micro-holographic saucers seem determined to take optical storage technology to the next level.
Apparently, these micro-holographic discs are in the laboratory stage and GE still has a long way to go before these discs can be made accessible to the common man. As it is, GE has put six years into the research of holographic storage technology and with Sony developing the Blu-ray technology furthermore, the effort could all go to waste.
