US Patent 7719951 - Inclined microtip data recorder
http://www.freepatentsonline.com/7719951.html
High density (i.e. >Terabit/cm2) data storage has been demonstrated using scanning probe tips having individual nanotubes fixed or grown onto a cantilever tip. However, using individual scanning probe tips limits the maximum rate of data reading and writing. This patent teaches using arrays of inclined carbon nanotubes tips formed on a flat substrate in order to increase read and write speeds. Claim 1 reads:
1. Data recording device, comprising
a network of carbon nanotubes constituting microtips cooperating with a substantially flat storage medium, device
wherein the carbon nanotubes are formed on a substantially flat substrate that is parallel to the storage medium, and are inclined with respect to the plane of the substrate.
