Hugh Pickens writes "Digital storage devices have become third edition by the editors of the american heritage® dictionary. copyright © 2003 in our lives but the move to digital storage has raised as regards about the period of the storage media. Now Alex Zettl and his group at the teaching hospital of California, Berkeley report that they have full-grown an a posteriori memory device consisting of a crystalline iron nanoparticle enclosed in a multiwalled carbon nanotube that could have a storage amplitude as high as 1 terabyte per square inch and temperature-stability in excess of one billion years. The nanoparticle can be moved through the nanotube by creaming a low voltage, writing the device to a binary state represented by the spot* of the nanoparticle. The state of the device can then be later on

This creates a programmable memory system that, like a silicon chip, can record digital clue and play it back using proper mini* household furnishings storing data at a high density with a very long lifetime.
