    摘要： For high track density recording, tighter reader and writer track width control are essential. This has been achieved by using a plated NiPd write gap which is self-aligned with a plated 23 KG pole material. Heat dissipation by the writer is thus improved since alumina has been replaced with nonmagnetic metal materials, such as Ru, leading to less pole tip protrusion which in turn leads to better writer track width control

    摘要： Aggressive (i.e. tight tolerance) stitching offers several advantages for magnetic write heads but at the cost of some losses during pole trimming. This problem has been overcome by replacing the alumina filler layer, that is used to protect the stitched pole during trimming, with a layer of electroplated material. Because of the superior step coverage associated with the plating method of deposition, pole trimming can then proceed without the introduction of stresses to the stitched pole while it is being trimmed.

    摘要翻译： 积极（即紧公差）缝合为磁性写入头提供了几个优点，但是在极修整期间以一些损失为代价。 通过用一层电镀材料替换用于在修整期间保护缝合极的氧化铝填料层已经克服了这个问题。 由于与沉积电镀方法相关的优越的台阶覆盖，因此可以进行极细修剪，而不会在缝合极被修剪时引入应力。

    摘要： A manufacturing process is provided where aggressive (i.e. tight tolerance) stitching offers several advantages for magnetic write heads but at the cost of some losses during pole trimming. This problem has been overcome by replacing the alumina filler layer, that is used to protect the stitched pole during trimming, with a layer of electroplated material. Because of the superior step coverage associated with the plating method of deposition, pole trimming can then proceed without the introduction of stresses to the stitched pole while it is being trimmed.
