Ultrahigh Density Data Storage Could Get Faster and Easier to Produce
Data storage density has doubled every three years since magnetic storage was first developed in the mid-1950s. Key technological innovations along the way such as giant magneto resistance (GMR), perpendicular magnetic recording (PMR) and heat-assisted magnetic recording (HAMR) have fueled that enormous growth in capacity. Despite this continually increasing storage density, there is a growing sense that this upward trend is beginning to lose steam.
Now researchers at the Helmholtz Zentrum Berlin (HZB) have developed a new technique with a new kind of material that could move magnetic storage technology beyond the current state-of-the-art HAMR technology and lead to faster and more energy efficient ultrahigh density data storage.
