A new nanotechnology manufacturing technique promises to boost storage capacity of Blu-ray discs by as much as twenty-fold and thus enable smaller, more powerful microprocessors.
Scientists at the University of California, Berkeley have invented the 'flying plasmonic head'. This is an array of metal lenses that focus light through excited electrons with a moving head that resembles the stylus on the arm of an old-fashioned LP turntable.
The head's ability to create nano-scale line patterns at high speed should revolutionise the field of optical lithography, a process that determines how small chips can be made, and how much information can be crammed on optical and hard discs.
