Disk technology takes Nobel Prize

French scientist Albert Fert and Peter Grunberg of Germany have won the 2007 Nobel Prize for physics.

The Nobel panel in Stockholm awarded Albert Fert of the University of Paris-Sud, in Orsay, France; and Peter Grunberg, of the Julich Research Center, in Julich, Germany, each with the medal and split the $1.5 million prize for the discovery of giant magnetoresistance.

The knowledge has allowed industry to develop sensitive reading tools to pull data off hard drives in computers, iPods and other digital devices. It has made it possible to radically miniaturise hard disks in recent years.
