Abstract: A high density magnetic recording medium including aggregates of magnetic nanoparticles arranged stably and efficiently in demarcated sections in the surface of a substrate is manufactured by the steps of forming a plurality of parallel tracks in the surface of the substrate, forming a plurality of minute recesses serially at approximately equal intervals in each of the tracks, casting a liquid dispersion of magnetic nanoparticles into the minute recesses, and evaporating dispersing medium from the liquid dispersion, thereby forming an aggregate of magnetic nanoparticles in each of the minute recesses.
Abstract translation: 通过在衬底的表面中形成多个平行轨道的步骤，制造包括在衬底表面中的分隔部分中稳定且有效地布置的磁性纳米颗粒聚集体的高密度磁记录介质，从而形成多个微小凹槽 在每个轨道中以大致相等的间隔，将磁性纳米颗粒的液体分散体注入到微小凹部中，并从分散体蒸发分散介质，从而在每个微小凹部中形成磁性纳米颗粒的聚集体。
