Accelerate Data Storage by Several Orders of Magnitude? Ultra-Fast Magnetic Reversal Observed
ScienceDaily (Apr. 19, 2011) â€” A newly discovered magnetic phenomenon could accelerate data storage by several orders of magnitude.
With a constantly growing flood of information, we are being inundated with increasing quantities of data, which we in turn want to process faster than ever. Oddly, the physical limit to the recording speed of magnetic storage media has remained largely unresearched. In experiments performed on the particle accelerator BESSY II of Helmholtz-Zentrum Berlin, Dutch researchers have now achieved ultrafast magnetic reversal and discovered a surprising phenomenon.
