摘要： A method for manufacturing a magnetic write head having a tapered write pole as well as a leading edge taper, and independent trailing and side magnetic shields. The method allows the write pole to be constructed by a dry process wherein the write pole material is either deposited by a process such as sputter deposition or electrically plated and the write pole shape is defined by masking and ion milling. The write pole has a stepped feature that can either be used to provide increased magnetic spacing between the trailing shield and the write pole at a location slightly recessed from the ABS or can be magnetic material that increases the effective thickness of the write pole at a location slightly recessed from the ABS. A bump structure can be further built over that stepped feature to enhance field gradient as well as reduce trailing shield saturation.
摘要翻译：一种用于制造具有锥形写柱以及前缘锥形的磁写头的方法，以及独立的后侧和侧面磁屏蔽。该方法允许写极通过干法进行构建，其中写极材料通过诸如溅射沉积或电镀的工艺沉积，并且写极形状通过掩模和离子铣削定义。写极具有阶梯特征，其可以用于在稍微从ABS处凹陷的位置处在后屏蔽和写极之间提供增加的磁间隔，或者可以是磁性材料，其增加写极的位置处的有效厚度从ABS略微凹进。可以在该阶梯特征上进一步构建凸块结构，以增强磁场梯度以及减少后屏蔽饱和度。

摘要： Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.
