Abstract

A method of constructing an air bearing on a single slider used as a support for a magnetic recording head is described. A recessed surface of the air bearing is constructed by: applying a polymerization initiator (preferably azomonochlorsilane), forming a pattern in the initiator, forming a polymer brush, and ion milling. The application of the polymerization initiator may be from solution or by stamping.
