>"The strategy the researchers used to write the data relies on a pair of lasers. The first, a green 515-nanometer laser, triggers spot formation, whereas the second, a red 639-nm laser, switches off the writing process. By controlling the time between firing of the lasers, the scientists could produce spots smaller than the wavelengths of light used to create them." Nice! More impressive, perhaps, than a 100+ layer CD/DVD/Optical Disk storing 1.6 PB or more in the future (and let's not kid ourselves -- that's pretty impressive!) -- is the process that gets us there... I wonder what other interesting applications this laser-based process could have in the future... Perhaps it could be used for future IC lithography (chip manufacturing) of some sort...
