Magnetic technology helps PC save data when power is lost

Three universities of Bath, Bristol and Leeds (UK) have found a way to control the magnetic field model correctly on thin film. Thus, they can be applied to improve memory capacity, a new breakthrough in magnetic storage technology.

The key to this new technique is that they use high-energy Galium ionic currents to control the direction of the magnetic field in regions on Cobalt film plate thickness of several atoms. The direction from this field will be used to store the information: "up" indicates the status on (number 1) and "down" indicates the closed state (number 0). Physicists also describe that the direction of magnetic fields can be "read" by measuring their resistance. This method will do the job faster than the current hard drive information reading technique because the "up and down" state only requires very short electrical impulses.

In addition, with new technology, the computer will never lose cached information even when power is lost because when the power is restored, the data will "re-export". " This result is very important because we can produce magnetic memory chips that never fall into the loss of information when electricity is abruptly cut ," said Simon Bending, Professor at Bath University. " This is the first time data is read and written quickly only with current technology ."
