A magnetic transducer head 10, for use in a magnetic data storage and retrieval system, comprises a substrate 12 with a reader 16 having a top shield 30 and a bottom shield 24. To reduce pole tip protrusion, at least one of the shields has a layer of material 46, 52 which has a lower coefficient of thermal expansion than the shield itself to compensate for the thermal expansion of the shield during operation. |
