With the advancement in technology and the rapid pace at which the Internet is expanding around us, data storage has become one of the most important technologies to focus on.
Magnetic Storage has been the backbone of this technological revolution, ever since it’s introduction in the 1950s. To keep the technology up to date, researchers have been working hard on new ways of improving the density of data storage.
These years of research have been really successful, as data storage density has doubled every three years since the inception of magnetic storage. However, despite this growth, there is a fear too that this upward trend is losing it’s steam.
This fear is riled up by the fact that the more small the bits of storage get, the more unstable they become. To take care of this issue, these bits are heated up with a focused light beam.
This method of using heat as a support system is known as Heat-Assisted Magnetic Recording (HAMR). However, the stability generated by this system is still limited and it requires a lot of heat to maintain.
Now, researchers at the Helmholtz Zentrum Berlin (HZB) are hoping to remove these limitations through the use of a new technique which might lead to faster and more energy efficient data storage.
Under this new technology, the iron-platinum materials that are typically used in HAMR-based data storage devices are replaced with thin films of the elements dysprosium and cobalt, which were sputtered onto a nanostructured membrane.
The structure made through the combination of these materials forms a honeycomb pattern in which the nanoholes are more stable than ever before.
In addition to the stability, the new structure is also a lot faster in terms of write patterns, while reducing the need of heat (only 80 Degrees) at the same time.
This way this new technology can offer more stable data storage, at faster speeds and less heat, thus pushing us into a new era of high density data storage solutions.
