Optical recording to increase DVD storage capacity by 300 times
In the ever evolving technological realm we witnessed the holographic discs that were rightly touted as the future of storage discs, given their capacity to store data equivalent to a 100 DVDs. But like in the mortal world where everything has a successor, the holographic disks may have found their heir in a new optical recording method, which will have discs storing 300 times the data stored on a standard DVD.
The unprecedented data capacity on a disc is the result of an effort by researchers at Swinburne University of Technology in Australia, who’ve used nanometer-scale particles of gold as a recording medium, churning the two spatial dimensions of DVDs and CDs into three dimensions for a process of five-dimensional optical recording. If this commercially feasibly tech that records information on 10 layers of the nano-rod films, in a range of different color wavelengths on the same physical disc can become real, then we are looking at 1.6 terabytes of data on a DVD-sized disc.
Having custom built multi-layer stacks, the team of researchers in an effort to find a commercial opening, are teaming up with Samsung to develop a drive that can read and record onto a DVD-sized disc. If Samsung is involved in the process then that affirmative notion will always linger on the edge, and therefore we can hope it will come.
