Heat Could Bring Hard Drive Performance Breakthrough
At the University of York in the United Kingdom, researchers led by Thomas Ostler have discovered a new way to improve hard disk drive (HDD) performance: Heat. The researchers discovered that by using a short burst of heat they could record data at a much faster rate. They accomplished this by hitting a magnet with a laser for less than one trillionth of a second, raising the temperature by an astounding 800 degrees Celsius. This short term burst of heat increases performance to levels hundreds of times faster than current HDDs. Essentially the method could allow for hard drives capable of recording terabytes of data per second, while lowering power consumption during the process.
Hard drives store data using magnetic recording, with tiny sections of the disc magnetized in a particular direction to represent the 0 or 1 of a bit. Recording data involves flipping the direction, which is currently done using an external magnetic field. Now, a team of researchers led by Thomas Ostler at the University of York, UK have discovered that a short burst of heat can do the job much faster.
