Hard disk storage and nanotechnology

Hard disks made of a nanosphere magnetic recording medium may offer simply stunning amounts of storage space.

From the link:

A new magnetic recording medium made up of tiny nanospheres has been devised by European researchers. The technology may lead to hard disks able to store more than a thousand billion bits of information in a square inch.

With consumer PCs now being sold with hard disks of a  or more – enough to record more than two years of music –  seems to be expanding without limit. But the limits are there and industry insiders know that they are approaching fast.

Also:

A spacing of 25 nanometres between spheres is equivalent to a storage density of one terabit (1000 gigabits) per square inch. Using the same approach with smaller spheres researchers should be able to attain densities up to six times higher.
