In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies.
We are here already.
This should provoke further conversation about how to manage and store our "stuff". OR the NSA's stuff, if we want to be blunt, because all our data is belong to them and now there are ways publicly posted on the intertubz that show a 1000x increase in capacity. What do we want to suppose that info is just for the consumption of us peons?
