Magnetic storage medium comprised of magnetic nanoparticles contained within nanotubes
View Patent ↗A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within nanotubes (e.g., carbon nanotubes).
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.
