摘要： The problem of increasing the output signal from a CCP-CPP GMR device without having it overheat has been overcome by placing materials that have different thermoelectric potentials on opposing sides of the spacer layer. Heat from the hot junction is removed at the substrate, which acts as a heat sink, resulting in a net local cooling of the confined current spacer layer, enabling it to operate at both higher input voltage increased reliability.

摘要： The possibility of shorting between a spin valve and its underlying magnetic shield layer can be largely eliminated by choosing the bottom spin valve structure. However, doing so causes the hard longitudinal bias that is standard for all such devices to degrade. The present invention overcomes this problem by inserting a thin NiCr, Ni, Fe, or Cr layer between the antiferromagnetic layer and the longitudinal bias layers. This provides a smoother surface for the bias layers to be deposited onto, thereby removing structural distortions to the longitudinal bias layer that would otherwise be present. A process for manufacturing the structure is also described.
摘要翻译：通过选择底部自旋阀结构，可以大大消除自旋阀与其下面的磁屏蔽层之间短路的可能性。然而，这样做会导致所有这些设备的标准硬的纵向偏差降级。本发明通过在反铁磁层和纵向偏置层之间插入薄的NiCr，Ni，Fe或Cr层来克服这个问题。这为偏压层沉积提供了更平滑的表面，从而消除了否则将存在的纵向偏置层的结构变形。还描述了用于制造该结构的方法。

摘要： A PMR writer having a trailing shield structure is disclosed in which a flux choking layer (FCL) formed adjacent to the ABS provides a means to limit the amount of flux flowing from the trailing shield to a first write shield (WS1) near the write pole tip thereby significantly reducing adjacent track erasure. The FCL has a substantially smaller thickness than a top section of the trailing shield to which it is attached along a side opposite the ABS. As a result, pole tip protrusion is reduced compared to prior art PMR writers. The FCL contacts a trailing side of WS1 at the ABS and one or both of the trailing sides of the WS1 and FCL may be tapered or perpendicular with respect to the ABS. The top trailing shield section, FCL, and WS1 may be comprised of NiFe, CoFe, CoFeNi, or alloys thereof.
