Abstract
A method and system provide a magnetic transducer including first and second read sensors, a shield and a conductive via. The shield is between the first and second read sensors. In one aspect, the magnetic transducer also includes first and second read shields. In this aspect, the first read shield has a read shield aperture. The conductive via extends through the read shield aperture, provides electrical contact to the shield and is insulated from the first read shield. In another aspect, the shield has first and second shield layers separated by an insulating layer. In this aspect, the second shield layer has an aperture therein. The conductive via extends through this aperture, provides electrical contact to the first shield layer and is insulated from the second shield layer.
