Data storage is a tricky business as we are constantly looking for better ways to store our data and to do it quicker. When it comes to the typical hard drives that we use daily it is all about using a magnetic field against a spinning magnetic disk inside of an enclosure. While the idea of using solid state memory is growing the standard is still the platter format we have been using since – well the first hard drives, so finding better ways to get data onto those platter is still important.
So this news from researches at York University in Toronto, Canada, about finding an interesting new way to store data on those spinning disks is pretty interesting. Instead of the typical magnetic field being applied the researchers use a heat pulse which allows for terrabytes of data to be stored on the drive each second.
That’s terrabytes folks and at a hundred times faster speed than conventional methods.
Conventional magnetic recording technology works by applying an external magnetic field to the recording medium to invert the direction of its magnetic poles, with stronger fields producing faster recording.
However, the researchers demonstrated that the positions of the magnetic poles can be inverted by an ultrashort heat pulse, harnessing the power of much stronger internal forces of magnetic media.
