SYSTEM, METHOD AND APPARATUS FOR PLANARIZING MEDIA TOPOGRAPHY VIA SOAKING IN DILUTE NON-FUNCTIONALIZED POLYMER SOLUTION

摘要

A method for planarizing media disk surfaces with a polymer solution is disclosed. A non-functionalized lubricant is used to coat the disk surfaces without dewetting issues. The polymer is applied via soaking in a diluted solution for several minutes. The interaction of the polymer with the disk surface leads to preferential adsorption of lubricant into the valleys of the topography on the disk surface.
