Abstract

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

Claims (12)

1. A method of reading information from magnetic storage media, comprising:

positioning a read-head over a magnetic storage media, said magnetic storage media comprising a plurality of nanotubes that each contain a magnetic nanoparticle, said read-head comprising a cantilevered piezoelectric nanostructure having a probe end;

deflecting said probe end with a magnetic polarization of a first magnetic nanoparticle contained within said magnetic storage media;

generating a piezoelectric response in the cantilevered piezoelectric nanostructure by the deflection of the probe end; and

determining the magnetic polarization of the first magnetic nanoparticle contained within said magnetic storage media by measuring the piezoelectric response of the cantilevered piezoelectric nanostructure.

2. The method of claim 1 , further comprising detecting servo control information from said magnetic storage media that is stored on a magnetic polarization of second magnetic nanoparticles contained within nanotubes within a servo sector.

3. The method of claim 2 , further comprising controlling said read-head with said servo control information.

4. The method of claim 2 , further comprising performing an error check to determine if said second magnetic nanoparticles were successfully polarized magnetically.

5. The method of claim 1 , further comprising reading data header information, said data header information stored on a magnetic polarization of a magnetic nanoparticle located within a data header location of a data sector.

6. The method of claim 1 , further comprising detecting a disk marker located on said storage media, said disk marker comprising a plurality of magnetic nanoparticles contained within nanotubes.

7. The method of claim 1 , further comprising performing an error check to determine if said first magnetic nanoparticle was successfully polarized magnetically.

8. The method of claim 1 , wherein said nanotubes are carbon nanotubes.
