Thanks for the micro-memories
Compared to solid state flash storage, the hard drive may seem like yesterday's tech. However, tomorrow's drives could squeeze in 200 times more data.
Scientists at the German Center for Free-Electron Laser Science (CFEL) have created a magnetic storage unit that occupies 4 x 16 nanometers on the disc. Each of its tooth-like structures is composed of 12 iron atoms, yet can store a single bit of data; the whole structure uses 96 atoms to hold a full byte.
This could lead to 100-terabyte drives, but don't hold your breath -- currently, the structure has to remain below -450 degrees Fahrenheit to be stable.
