One of the goals of computing since the 1950s has been to shrink hard drives and allow them to store much more information. This has led to hard drive technology on a nanoscale.
Previously electricity was used to read data stored magnetically on the hard drive. The next big leap came in the 1980s when scientists invented 'spintronics'.
