Okay, so there's no magic product (yet) that will literally burn three terabytes onto a writeable CD, but Harvard researchers are certainly getting closer to making it happen. The group has developed an "optical nano antenna" that's built onto an inexpensive, off-the-shelf antenna in order to bypass that pesky diffraction limit that prevents current lasers from focusing light onto a smaller spot than half its native wavelength. By utilizing two gold "nano rods" separated by a 30 nanometer gap, they have devised a method for a laser sporting an 830 nanometer wavelength to focus its beam onto a 40 nanometer area, allowing for mind boggling amounts of data to be written to an optical disc. While the integrity of the burn is more than sketchy using such a high resolution beam, the team of engineers are hard at work trying to improve and perfect the space-saving process. Until then, we suppose we're still stuck paying an arm and a leg (or two) for those spacious, burnable Blu-ray / HD DVD discs.
