physics.berkeley.edu - Our memory device consists of a crystalline iron nanoparticle enclosed in a multiwalled carbon nanotube.  The nanotube can be reversibly moved through the nanotube by applying a low voltage, "writing" the device to a binary state represented by the position of the nanoparticle.  The state of the device can then be subsequently read by a simple resistance measurement.

Thus begins the abstract that introduces a natural in the storage industry, more density, but with the twist of longer life. From a quick review, it appears that the density increase over current magnetic media is less than an order of magnitude, but the lifetime of expected durability is 4 orders of increase.

The post production archive industry would be the beneficiary of this leap. Estimates by the Arts and Science group at the Academy give film the nod over magnetic media since the latter constantly has to be refreshed.
