Data storage medium surface smoothing method and associated apparatus

A method for smoothing a medium includes depositing a magnetic layer onto a base, depositing an overcoat layer onto an outer surface of the magnetic layer, and burnishing an outer surface of the overcoat layer. Further, the method includes at least one of (i) directing a first ion beam comprised of...

Summary:A method for smoothing a medium includes depositing a magnetic layer onto a base, depositing an overcoat layer onto an outer surface of the magnetic layer, and burnishing an outer surface of the overcoat layer. Further, the method includes at least one of (i) directing a first ion beam comprised of first energetic ions toward the outer surface of the magnetic layer at a first shallow grazing angle and smoothing the outer surface of the magnetic layer via etching engagement between the first ion beam and the outer surface of the magnetic layer; and (ii) directing a second ion beam comprised of second energetic ions toward the outer surface of the overcoat layer at a second shallow grazing angle and smoothing the outer surface of the overcoat layer via etching engagement between the second angled ion beam and the outer surface of the overcoat layer.
