Abstract

Official abstract text for this publication.

A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within nanotubes (e.g., carbon nanotubes).

First claim

Opening claim text (preview).

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A nanostructure assembly comprising: a first nanotube assembly having nanotubes containing magnetic nanoparticles magnetically polarized in a uniform direction to indicate a first digital state; and a second non-magnetic nanotube assembly having nanotubes containing non-magnetic nanoparticles within individual nanotubes to indicate a second digital state. 2. The nanostructure assembly of claim 1 , wherein the nanostructure assembly carries a gray code. 3. The nanostructure assembly of claim 2 , wherein the gray code is located within a servo sector. 4. The nanostructure assembly of claim 1 , wherein the nanotube assemblies are encapsulated within a matrix. 5. A nanostructure assembly comprising: a first nanotube assembly having nanotubes that include magnetically polarized magnetic nanoparticles, wherein the first nanotube assembly is configured to carry an error-correction code; and a second nanotube assembly having nanotubes containing non-magnetic nanoparticles within individual nanotubes. 6. A nanostructure assembly capable of being arranged to form a gray code, the nanostructure assembly comprising: a first nanotube assembly having nanotubes that include magnetic nanoparticles magnetically polarized in a uniform direction to indicate a first digital state; and a second nanotube assembly having nanotubes containing non-magnetic nanoparticles within individual nanotubes to thereby indicate a second digital state, wherein the first nanotube assembly and the second nanotube assembly at least partially form the gray code. 7. A nanostructure assembly comprising: a first nanotube assembly having nanotubes containing magnetic nanoparticles magnetically polarized in a uniform direction to indicate a first digital state; and a second non-magnetic nanotube assembly having nanotubes containing only non-magnetic nanoparticles within individual nanotubes to indicate a second digital state.
