From day to day, hard disks tend to be smaller, faster, cheaper, and larger capacity. However, its development has been limited by the needs of even smaller components. The size of the current components to the development of the hard disk is inhibited. That is what underlies the researchers to develop biocomputing involving biological molecules in the manufacture of microscopic electronic components.
Researchers at the Leed United Kingdom University and Tokyo University of Agriculture and Technology have found a new player with huge potential, the iron-eating bacteria. Bacteria called magnetospirillum magneticum live in water that has the ability to organize itself according to the position of Earth's magnetic field. If these bacteria "eat" the iron, it will produce magnetite (small magnetic grains) in it. This magnetic grains can then be molded into the surface of the magnet as in the traditional hard disk.
If the research is successful, we will see a new type of hard disk that can be of buttons, but its capacity to reach 8 terabytes per square inch! PC or server in the pocket was not impossible. Look forward to it in the next 10 years, according to the promise of "Dr. Sarah Staniland" from the University of Leed.
