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.
