Abstract:
A read transducer having a first read sensor, a second read sensor, and a first middle shield is provided. The second read sensor is disposed in a down track direction from the first read sensor. The first middle shield is disposed between the first read sensor and the second read sensor. The first middle shield includes a first metallic middle shield layer disposed between the first read sensor and the second read sensor, a second metallic middle shield layer disposed between the first metallic middle shield layer and the second read sensor, and a first magnetic-spacer layer disposed between the first metallic middle shield layer and the second metallic middle shield layer. The first metallic middle shield layer and the second metallic middle shield layer have substantially the same polarity.
