Disk technology takes Nobel Prize

French scientist Albert Fert and Peter Grunberg of Germany have won the 2007 Nobel Prize in physics after discovering the phenomenon of "giant magnetoresistance" (GMR), in which weak magnetic changes give rise to big differences in electrical resistance. The knowledge has allowed the development of sensitive reading tools to pull data off hard drives in computers and portable digital devices. GMR, which involves structures consisting of very thin layers of different magnetic materials, has made it possible to radically miniaturise hard disks in recent years.

For this reason it can also be considered "one of the first real applications of the promising field of nanotechnology. Applications of this phenomenon have revolutionised techniques for retrieving data from hard disks. The discovery also plays a major role in various magnetic sensors as well as for the development of a new generation of electronics," according to the Royal Swedish Academy of Sciences. A hard disk stores data in the form of microscopic areas that are magnetised in different directions. The information is retrieved by a read-out head that scans the disk and registers the magnetic changes. The smaller and more compact the hard disk, the smaller and weaker the individual magnetic areas - more sensitive read-out heads are therefore needed when more information is crammed on to a hard disk.

Just what we need even bigger faster hard disks, so software developers can increase the size of their bloatware, thus increasing employee count. What happened to the days of "you'll never use ~~" (fill in the blank, depending on age and experience.) No wonder people need Google Search (another huge database) to find what they did with their files. And then have a major alert, when a laptop gets nicked, containing 10 million patients records, of mortgage details, customer records etc.

Will this madness ever stop? Hopefully next year someone will get a prize for working out a painless way of reducing world population (and not one of the nasty CFR, Rockefeller funded methods! )

"A computer hard-disk reader that uses a GMR sensor is equivalent to a jet flying at a speed of 30,000 kmph, at a height of just one metre above the ground, and yet being able to see and catalogue every single blade of grass it passes over."

Cool, eh?

In other news, the US Defense Department announced that it has contracted with an unnamed European scientist to develop a jet that can fly at speed of 30,000 kmph, at a height of just one meter above the ground, and yet being able to see and catalog every single blade of grass it passes over.
