An unbelievable half a terrabit per square inch, Crestec, the company behind the next generation hard drives have named the new technology ‘patterned media disks’

Crestec’s machine creates the disk master by burning tiny holes in concentric circles on a resistant material that’s spread on a silicon substrate. Each hole has a diameter of 10 nanometers. After e-beam processing, the substrate is etched, which creates pits in the silicon where there were holes. Currently, the machine spaces the pits 35nm apart.
