摘要: A magnetic head has an air bearing surface, a substrate, data transducer and composite overcoat layer. The is positioned upon the substrate adjacent surface. includes plurality of metallic layers. layer on side opposite substrate. An effective coefficient thermal expansion substantially equal to material forming
