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.
