The science behind minature hard disk garners a nobel prize

The 2007 Nobel prize for physics was awarded to Albert Fert of France and Peter Grunberg of Germany. Their research was lauded as being both practical and relevant to industry.
Their discovery powers devices such as mp3 players. The phenomenon is called “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.
The discovery was initially made in the 1980s and allows large amounts of data to be read and written to hard drives.
