Abstract: Apparatus and methods to sequence DNA. A DNA sequencing device includes a passage, a first electrode, and a second electrode. The passage has a width and a length. The first and second electrodes are exposed within the passage and spaced apart from each other to form an electrode gap. The electrode gap is no greater than about 2 nm. The DNA sequencing device is operable to measure with the first and second electrodes a change in electronic signal in response to nucleotides of a DNA strand passing through the electrode gap.

Abstract: A method of forming patterned magnetic media disclosed herein includes patterning a guiding layer on a substrate to form a nucleation guiding pattern. A layer of magnetic material is formed over the nucleation guiding pattern. The magnetic material may comprise a non-magnetic segregant. Magnetic grains are grown in a down-track direction and in a cross-track direction responsive to the nucleation guiding pattern and the non-magnetic segregant forms grain boundaries between the magnetic grains.

Abstract: A data storage medium may have increased data capacity by being configured with first and second patterned pedestals that are each separated from a substrate by a seed layer. A first polymer brush layer can be positioned between the first and second patterned pedestals atop the seed layer and a second polymer brush layer may be positioned atop each patterned pedestal. The first and second polymer brush layers may be chemically different and a block copolymer can be deposited to self-assemble into separate magnetic domains aligned with either the first or second polymer brush layers.
