The breakthrough has been made in the research of bit-patterned media, a magnetic storage technology that is being developed for future hard disk drives. In today's drives, magnetic material is spread across the surface of the disk and bits of data are stored across several hundred magnetic grains, but the technology is reaching its limit.More details at IT World.
Bit-patterned media breaks up the recording surface into numerous magnetic bits, each consisting of a few magnetic grains. Under a microscope, the magnetic bits look like thousands of tiny spheres crammed next to each another.
Data is stored on these magnetic bits: One magnetic bit can hold one bit of data.
