French scientist Albert Fert and Peter Grunberg of Germany have won the 2007 Nobel Prize for physics.
They discovered the phenomenon of "giant magnetoresistance", in which weak magnetic changes give rise to big differences in electrical resistance.
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.
