How to Burn a Three Terabyte CD

`A new nano-optical device can focus laser light tighter than traditional optics, which could lead to higher-density data storage.

A computer simulation of the optical nano antenna that Harvard researchers have fabricated. Consisting of two gold-coated nano rods separated by a 30-nanometer gap, the antenna can focus light from a commercial laser to a spot just 40 nanometers wide. It could be used to write terabytes, rather than gigabytes, of data to a CD or DVD.’
