Abstract
A method, according to one approach, includes forming an underlayer of a magnetic recording medium. The underlayer includes encapsulated nanoparticles each comprising a magnetic nanoparticle encapsulated by an aromatic polymer, and a polymeric binder binding the encapsulated nanoparticles. The underlayer is cured by irradiating the underlayer for causing crosslinking of the polymeric binder. In another approach, a method includes forming an underlayer of a magnetic recording medium by spray coating a mixture of a magnetic nanoparticles, aromatic polymer, and polymeric binder onto a structure as a sprayed-on aerosol coating; and curing the underlayer.
