The researchers have reported that they are working towards a methods which will enable the gadgets to have enough memory to store about 300 million songs.
The researchers said that they created a minuscule switch that could squeeze up to one million gigabytes of memory on to one square inch.
“What we have done is find a way to increase the data storage capabilities in a radical way," says Professor Lee Cronin.
The research team explained that the molecular switch is controlled by taking nanoparticles, each a millionth of a millimeter in size, and are placed on a gold or carbon surface.
Dr Vin Dhanak of the STFC Daresbury Laboratory, said: “This research shows the potential is there for your future iPod to have hundreds of thousands times more capacity to store music and video than is currently possible."
The biggest challenge which the researcher have is to resolve “fabrication issues".
