Special Molecules to Enhance Storage of Hard Drives, says study


In the last few years, the fundamental unit of storage media has reached to the lowest possible size, beyond which it is challenged by fundamentals of quantum mechanics. However, in a new technique spin-crossover molecules have been involved as the smallest unit of storage, the details of the technique and its execution have been published in the scientific journal Nano Letters.

Akin to normal hard drives, spin-crossover molecules can save data via their magnetic state. This requires the special molecules to be positioned on surfaces. This is challenging to place the spin-crossover molecules on surface without damaging their capability to store information.

Outcome of Study could Possibly Increase Storage Capacity of Hard Drives Manifold

In a study conducted at Kiel University, researchers have been able to place spin-crossover molecules on a surface, and have also been successful to use interactions which were earlier considered to pose a challenge for improving the storage capacity of the molecule. As a result of this finding, theoretically, storage density of traditional hard drives could be increased by a degree of over one hundred times, and data carriers could be reduced to a much smaller size.

The technology currently used to store data on hard drives is challenged by the fundamental limits of quantum mechanics owing to the size of the Bit. This cannot reduce further, as stated by an associate at the Institute of Experimental and Applied Physics at Kiel University. The study involved using a single molecule to encode a Bit, with the objective to demonstrate the principle that even smaller hard drives with more storage could be a possibility in the future.
