A team of international researchers has shown an innovative way of magnetic recording that will allow data to be processed faster than the present hard drive technology.
The scientists identified that only by means of heat, the information can be recorded. They have considered that this new discovery will accelerate future magnetic recording with more energy efficiency.
Nature Communications in its February edition has reported the results of the research that was conducted by the University of York’s Department of Physics.
Thomas Ostler, University of York physicist stated that the researchers connected more strong internal forces and recorded the data using heat, instead of applying a magnetic field for recording data on a magnetic medium. This new process has allowed the recording of terabytes of data per second and is hundred times quicker than the current hard drive technology. Less energy is utilized, because magnetic field is not required.
The international scientist team includes researchers from Japan, the Netherlands, Russia, Switzerland, Spain and Ukraine. Experiments were conducted at the Radboud University Nijmegen, Netherlands, Paul Scherrer Institut in Switzerland and the Ioffe Physical Technical Institute of the Russian Academy of Sciences.
Dr Alexey Kimel, from the Radboud University Nijmegen’s Institute of Molecules and Materials, stated that heat was believed to be the destroyer of the magnetic field. It has currently confirmed that it may be act as a stimulus for recording data on a magnetic medium.
The scientist team has confirmed that an ultrashort heat pulse can invert the magnet’s north and south poles position and connect the power of strong internal forces of magnetic medium.
