摘要
An apparatus, according to one embodiment, includes: a transducer structure having: a lower shield, an upper shield above the lower shield, a current-perpendicular-to-plane sensor between the upper and lower shields, an electrical lead layer between the sensor and one of the shields, and a spacer layer between the electrical lead layer and the one of the shields. The upper and lower shields provide magnetic shielding. The electrical lead layer is in electrical communication with the sensor. A conductivity of the electrical lead layer is higher than a conductivity of the spacer layer. A width of the electrical lead layer in a cross-track direction is greater than the width of a free layer of the sensor.
