The discovery allows for twice the bit density of today's disk drives. Nanolithography was used to make dense patterns of "magnetic islands" that appear as small dots in about 100,000 circular tracks required for disk drives.
This pattern has 1.2 trillion dots per square inch, showing the dense patterns of magnetic islands made by HGST Labs using such emerging nanotechnologies as self-assembling molecules, line doubling and nanoimprinting. Each dot can store a single bit of data (Source: HGST).
