摘要： A PMR writer with a tapered main pole layer and tapered non-magnetic top-shaping layer is disclosed that minimizes trailing shield saturation. A second non-magnetic top shaping layer may be employed to reduce the effective TH size while the bulk of the trailing shield is thicker to allow a larger process window for back end processing. A sloped surface with one end at the ABS and a second end 0.05 to 0.3 microns from the ABS is formed at a 10 to 80 degree angle to the ABS and includes a sloped surface on the upper portion of the main pole layer and on the non-magnetic top shaping layer. An end is formed on the second non-magnetic top shaping layer at the second end of the sloped surface followed by forming a conformal write gap layer and then depositing the trailing shield on the write gap layer and along the ABS.

摘要： A process (and the structure resulting therefrom) is described for manufacturing a magnetic write head in which there is no physical interface between the first and second trailing shields. This is achieved by laying down a sacrificial layer which is patterned to extend inwards towards the top yoke whereby the dimensions and shapes of the shields are defined.

摘要： A perpendicular magnetic recording (PMR) head is fabricated with a tapered main pole having a variable thickness. The tapered portion of the pole is at the ABS tip and it can be formed by bevels at the leading or trailing edges or both. The taper terminates to form a region with a maximum thickness, t1, which extends for a certain distance proximally. Beyond this region of maximum thickness t1, the pole is then reduced to a constant minimum thickness t2. A yoke is attached to this region of constant minimum thickness. This pole design requires less flux because of the thinner region of the pole where it attaches to the yoke, but the thicker region just before the tapered ABS provides additional flux to drive the pole just before the ABS, so that high definition and field gain is achieved, yet fringing is significantly reduced.
摘要翻译：制造具有可变厚度的锥形主极的垂直磁记录（PMR）头。极的锥形部分在ABS尖端处，并且其可以由前缘或后缘处的斜面或两者形成。锥形终止形成最大厚度的区域t1，其向近处延伸一定距离。超过该最大厚度的区域t1，然后将极减小到恒定的最小厚度t2。磁轭连接到恒定最小厚度的区域。这个极设计需要更少的通量，因为它附着在磁轭上的磁极的较薄区域，而刚好在锥形ABS之前较厚的区域提供额外的磁通来驱动刚好在ABS之前的极点，因此高清晰度和场增益是实现了，但边缘明显减少。

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。
