According to current estimates, dozens of zettabytes of information will be stored electronically by 2020, which will rely on physical principles that facilitate the use of single atoms or molecules as basic memory cells. This can be done using lasers. However, existing methods of optical storage are limited to the diffraction limit (~500 nm), so the respective recording density is roughly ~1 Gb per square decimeter.
