用于接触记录传感器的导电磁屏蔽层压结构

Electrically conductive magnetic shield laminate structure for contact recording sensor
Abstract:
In one general embodiment, an apparatus includes a magnetic sensor structure, a magnetic shield having at least one laminate pair comprising a magnetic layer and an electrically conductive nonmagnetic layer, and a nonmagnetic spacer layer between the sensor structure and the magnetic shield. In another general embodiment, an apparatus includes a magnetic tunnel junction sensor structure, and a magnetic shield having at least two laminate pairs, each pair comprising a magnetic layer and an electrically conductive nonmagnetic layer. A deposition thickness of the nonmagnetic layer in each laminate pair is about 10% or less of a total deposition thickness of the laminate pair.
