Atomic-scale memory can store 500 times more than today’s best hard drive

Dutch researchers have discovered a method of storing atom-sized bits on copper with a density of 500 Terabits per square inch (Tbpsi) -- 500 times more dense than the best commercial hard disk currently available.
"In theory, this storage density would allow all books ever created by humans to be written on a single post stamp," lead scientist Sander Otte said in a statement.
The research, published today in the journal Nature Nanotechnology, details how the scientists were able to construct a
