<p>The surface of a substrate for a magnetic recording medium is processed with a plasma so as to impart an arbitrary uniform surface roughness to the substrate without removing principal elements in the surface of the substrate with ions or free radicals in the plasma. It has become possible to prevent the adhesion of a magnetic head to the magnetic recording medium, enhance the reliability, to lower the flying height of the magnetic head, to increase TPI through the isotropy of the magnetic characteristics, and to lower the noise of recording. Also a highly reliable magnetic storage having a high recording density can be realized.</p> |
