Eternal media: 360 terabytes on a quartz disk
Do you want to save the information literally forever? Then what could be better than a technique that uses a laser to store 360 terabytes of information on nanostructured drive. This data does not happen ... as much as 14 billion years. < Website published an article explaining the details.
developed by researchers at Southampton University in the UK, the technique uses a femtosecond laser pulses to record data in three-dimensional silica structure on the nanoscale. The pulses create a three layer nanostructured points with a distance of five microns between them. Changes in the structure can be read by using another pulse of light and the writing polarization - the direction of the waves -. After its passage
Scientists have recorded on small glass disks a number of books, including the Universal Declaration of Human Rights, the "optics" of Isaac Newton, the Magna Carta, and the King James Bible. The density of information on these discs is so high that one quartz plate can accommodate 360 terabytes. Moreover, this information will be extremely stable: it can be preserved for 13, 8 billion years, maintaining the temperature at 177 degrees Celsius
The video shows the recording process on quartz disks:.
