Abstract
A hard disk drive slider comprises an overcoat layer, which covers an air-bearing surface of the slider. The overcoat covers an exposed surface of a tunneling magnetoresistance transducer. An adhesion layer is coupled with the overcoat layer and the air-bearing surface. The adhesion layer comprises a compound of nitrogen. The compound of nitrogen reduces noise in read data from the tunneling magnetoresistance transducer.
