    Abstract: In accordance with one embodiment, an apparatus includes a main pole layer of magnetic material; a second layer of magnetic material; a first gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; wherein the second gap layer of non-magnetic material is disposed directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. A method of manufacturing such a device is also described.

    Abstract translation: 根据一个实施例，一种装置包括磁性材料的主极层; 第二层磁性材料; 设置在所述主极层和所述第二磁性材料层之间的非磁性材料的第一间隙层; 设置在主极层和第二磁性材料层之间的非磁性材料的第二间隙层; 其中所述非磁性材料的所述第二间隙层直接邻近所述第二磁性材料层设置。 根据一个实施例，这允许间隙用作第二层磁性材料的非磁性种子。 还描述了制造这种装置的方法。
