摘要： A magnetic sensor having a novel hard bias structure that provides reduced gap spacing for increased data density. The magnetic sensor includes a sensor stack with first and second sides formed on a magnetic shield. A thin insulation layer is formed over the sides of the sensor stack and over the bottom shield. An under-layer comprising Cu—O is formed over the insulation layer and a hard magnetic bias layer is formed over the under-layer. The use of Cu—O as the under-layer allows the under-layer to be made thinner while still maintaining excellent magnetic properties in the hard bias layers formed thereover. This reduced thickness of the under-layer allows the gap spacing (spacing between the top and bottom magnetic shields) to be reduced, which in turn provides increased data density.
