A new writing method uses heat instead of external magnetic fields

A method has been invented that will monumentally accelerate the transfer speeds of hard drive units.

A team of physicists has discovered a new way to write data on magnetic storage units.

Data on HDD platters is recorded by inverting the poles of a magnet. So far, this inversion has been achieved through the application of an external magnetic field.

Scientists have now demonstrated that the position of the North and South poles of a magnet can be inverted by an ultrashort heat pulse as well.

In other words, the internal attraction forces of a magnet are harnessed. The process can supposedly boost HDD speed by a factor of 100, or more.

There is no telling when practical applications will show up, but we hope it's soon. Go here where we wrote about the technology at length.
