    摘要： The invention offers a magnetic recording head that includes a substrate, a read sensor, and at least one shield positioned adjacent to the read sensor, wherein the shield contributes to thermal pole-tip recession in an amount less than about 0.5 Å/° C. The invention also offers a magnetic recording head that includes a substrate having a coefficient of thermal expansion, a read sensor, and at least one shield, positioned adjacent to the read sensor, that has a coefficient of thermal expansion within ±2×10−6/° C. of the coefficient of thermal expansion of the substrate. The invention further offers a magnetic recording head that includes a substrate, a read sensor, and at least one shield, positioned adjacent the read sensor, with a thickness of from about 0.05 μm to about 0.5 μm.

    摘要： The present disclosure provides a magnetic recording head for a data storage system having improved write field characteristics. In one example, an apparatus having magnetic properties is provided. The apparatus includes a pole, a shield, and a multilayer block positioned between the pole and the shield. The multilayer block includes a plurality of layers wherein at least one of the plurality of layers comprises a magnetic material. In one embodiment, the multilayer block provides an antiferromagnetic coupling between the pole and the shield such that a magnetization of the pole is in a first direction and a magnetization of the shield in a second direction that is substantially anti-parallel to the first direction.
