Abstract

See full text

According to one embodiment, a magnetic recording medium includes: a substrate; an underlayer positioned above the substrate; a magnetic recording layer positioned above the underlayer; and a plurality of conductive polymers dispersed within the substrate, the underlayer, the magnetic recording layer, the substrate and the underlayer, the substrate and the magnetic recording layer, the underlayer and the magnetic recording layer, or the underlayer, the magnetic recording layer, and the substrate. In addition, the conductive polymers are dispersed such that a concentration of the conductive polymers has a gradient in a single one of the layers in a thickness direction.
