More and more storage capacity
Hard drives keep getting larger capacities. Two terabyte drives are now available. But the current data storage technology has a limit so researchers keep looking for new ways to store data. A recent discovery finds that using certain polymers on a sapphire surface can give 15 times the data density of present devices. Computerworld reports on the new technology
Nanotechnology researchers say they have achieved a breakthrough that could fit the contents of 250 DVDs on a coin-size surface and might also have implications for displays and solar cells.
The scientists — from the University of California, Berkeley, and the University of Massachusetts, Amherst — discovered a way to make certain kinds of molecules line up in perfect arrays over relatively large areas.

The nanolaser is an important step toward a disk-writing system that many researchers are currently working on. Such a system would use both light and magnetic fields to store data on a disk, packing up to 50 terabits per square inch of data.
