US Patent 7153597 - Nanoparticle Magnetic Memory

For data storage densities approaching the a Terabit/in2 nanoparticle magnetic material are usefully applied to suppress noise over more conventional magnetic recording media. In order to pattern such nanoparticles in an ordered array so as to be useful for magnetic storage this patent employs a self-assembled monolayer deposited in segmented pits. Claim 1 reads:

1. A device for magnetic recording comprising: a substrate having a locking pattern formed therein, the locking pattern comprising a plurality of pits formed in the substrate; a self-assembled monolayer (SAM) deposited on the substrate in the plurality of pits; and a first layer of nanoparticles deposited on the SAM in the plurality of pits and chemically bonded to the substrate via the SAM.
