Neutralizing flying height sensitivity of thermal pole-tip protrusion of magnetic slider

A method for neutralizing flying height sensitivity of a magnetic slider thermal pole-tip protrusion, the method comprising:

• (a) creating head material data about one or more respective materials, said head material data comprising at least one material property that is dependent on the fabrication process used to fabricate said one or more respective materials;
• (b) creating air bearing surface (ABS) compensation data about the dependence of ABS compensation on one or more respective ABS features, said ABS compensation data comprising how said respective ABS features affect air bearing pressure;
• (c) creating a head and ABS design based on said head material data and said ABS compensation data;
• (d) determining a change in flying height at respective temperatures for said head and ABS design;
• (e) determining whether said change in flying height meets a particular flying height design criteria involving flying height sensitivity to temperature changes;
• and
• (f) if said change in flying height meets said particular flying height design criteria, then manufacturing an air bearing slider based on said head and ABS design;
• (g) if said change in flying height does not meet said particular flying height design criteria, then modifying said head and ABS design based on said head material data and said ABS compensation data and repeating (c)-(g).
