A slider for a head to read data from or write data to a magnetic media is disclosed. The slider includes an air bearing surface including raised bearing surface(s) elevated above recessed bearing surface(s) to pressurize air flow along the air bearing surface to provide a fly height for the slider above the media. The raised bearing surfaces are formed along one or more raised substrate structures etched from a substrate body. The slider includes one or more insets inset into the one or more raised substrate structures formed of an inset material having a different coefficient of expansion than a substrate material of the slider to compensate for temperature and/or humidity changes.
