Optical test set-up using a 405 nm laser
Optical disk test set-up built by Martin Salt from the Institute of Microtechnology, University of Neuchâtel (Switzerland) and Peter Török from Imperial College (UK). The one Terabyte disk would be double sided and dual layer, but even the team's single sided version could hold the Lord of the Rings trilogy 13 times over, or all 238 episodes of Friends.
