ABSTRACT:
Method for texturing a surface of a metallic thin film of a magnetic disk substrate comprising the steps of: (a) frictionally contacting the surface of the metallic thin film with an abrasive article, wherein the abrasive article comprises an abrasive coating including a water-soluble binder and abrasive particles, wherein the abrasive coating is adhesively attached to a flexible foraminous fibrous backing; and (b) abrading the surface of the metallic thin film by moving the metallic thin film and the abrasive article relative to one another with the abrasive coating in contact with an aqueous liquid solution to form scratches in the surface of the metallic thin film, wherein the liquid solution is free of abrasive particles before contact is initiated with the abrasive coating.
