HIGH DENSITY MAGNETIC RECORDING MEDIUM AND MANUFACTURING METHOD THEREOF

摘要

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.
