British scientists say they have discovered a method for storing and retrieving huge amounts of digital data that could last for over a million years.
Using extremely short and intense pulses of laser light, researchers at the University of Southampton assembled structures in fused quartz glass that can withstand temperatures up to 1000 degrees Celsius.
The data, written in three layers of nanometer sized structured dots, can be read by an optical microscope with polarized lenses. A …
