The CD of the future will have the capacity of 200.000 DVDs

More capacity and less space. One of the premises that develop the technology of the future will also be applied to the CD format. According to The Inquirer, scientists at the University of Swiburne are developing a nanotechnology project that aims to include a petabyte on a single disk, or in other words, it would support an amount of data 20.000 times greater than that of Blu-ray. So in the future a CD could store up to 200.000 DVDs on a single disc.

The project, which has a duration of five years and a million dollar budget, runs through its third part of the following thesis: a normal CD has a thickness of 1,2 millimeters, but the information stored on it with current technology would take up 0,1% of the total volume so 99,9% of the disk space is wasted. So the project aims to use a series of techniques, one of the most significant involves increasing the number of layers in which data can be stored. Scientists estimate that they can reach up to 300 layers, which would be a considerable increase considering that a current CD only has 4 layers.
