ALEXANDRIA, Va., Aug. 19 -- Sigma Pro, Dover, Del., has been assigned a patent (8,507,032) developed by Tyson York Winarski, Washington, for an "orientation of nanotubes containing magnetic nanoparticles in a magnetic storage medium."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A magnetic storage medium is formed of magnetic nanoparticles that are encapsulated within nanotubes (e.g., carbon nanotubes), which are arranged in a substrate to facilitate the reading and writing of information by a read/write head. The substrate may be flexible or rigid. Information is stored on the magnetic nanoparticles via the read/write head of a storage device. These magnetic nanoparticles are arranged into data tracks to store information through encapsulation within the carbon nanotubes. As carbon nanotubes are bendable, the carbon nanotubes may be arranged on flexible or rigid substrates, such as a polymer tape or disk for flexible media, or a glass substrate for rigid disk. A polymer may assist holding the nano-particle filled carbon-tubes to the substrate. Magnetic fields may be applied to draw the carbon nanotubes into data tracks and orient the carbon nanotubes within the data tracks."
The patent application was filed on March 13, 2009 (12/403,729). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8507032.PN.&OS=PN/8507032&RS=PN/8507032
