Million-song MP3 players on way
A NEW generation of MP3 players could provide music lovers with millions of songs at their fingertips.
Scientists have developed a way of dramatically increasing the memory on iPods and other gadgets while retaining their small size.
Future devices could store 150,000 times the amount of models on the market now, according to researchers at Glasgow University.
They have created a tiny switch which would see 500,000 to one million gigabytes squeezed on to one square inch.
The current limit is around 3.3 gigabytes. The technology is being developed along with scientists at the STFC Daresbury Laboratory in Warrington, England.
Dr Vin Dhanak of the laboratory said: “This research shows that the potential is there for your future iPod to have hundreds of thousands times more capacity to store music and video than currently possible.”
The team now faces the challenge of resolving “fabrication issues'' surrounding the device.
The molecular switch is controlled by taking nanoparticles, each a millionth of a millimetre in size, and placing them on to a gold or carbon surface.
The research is reported in this month's edition of the journal Nature Nanotechnology.
