Nanotechnology increases storage capacity

Can you even imagine an MP3 player with a 500,000 GB capacity? It’s pretty much beyond belief. The most generous player today can only hold around 40,000 songs – they’d hardly make a dent on this.
The thing is, it could easily happen. Scientists at the University of Glasgow have created a nanotechnology breakthrough that could increase storage capacity by 150,000 times. It could mean 500,000 GB on a single chip and inch square.
The Glasgow scientists worked to create the molecule-sized switch that’s at the heart of it all.
Professor Lee Cronin at the University of Glasgow said,
“What we have done is find a way to potentially increase the data storage capabilities in a radical way. We have been able to assemble a functional nanocluster that incorporates two electron donating groups, and position them precisely 0.32 nm apart so that they can form a totally new type of molecular switching device. The key advantage of the molecule sized switch is information / transistor density in traditional semi-conductors. Molecule sized switches would lead to increasing data storage to say 4 Petabits per square inch.
