摘要： A manufacturing method of a thin-film magnetic head with a dishing suppressed in the case of planarizing a magnetic shield which a read head portion has or a magnetic pole which a write head portion has is provided. A manufacturing method of a thin-film magnetic head comprising a read head portion for data reading which has at least two magnetic layers functioning as a magnetic shield and a write head portion for data writing which has two magnetic layers functioning as a magnetic pole is provided, in a process forming at least the lowest magnetic layer in at least the two magnetic layers functioning as the magnetic shield and the two magnetic layers functioning as the magnetic pole in the case of forming a plurality of thin-film magnetic head patterns on an element formation surface of the wafer substrate, which comprises steps of: forming this magnetic layer so as to reach a position which becomes a medium opposed surface at a middle portion to a trick width direction in each thin-film magnetic head pattern, and forming a dishing prevention portion at a position farther than this magnetic layer from the position which becomes the medium opposed surface in both sides or either side along the track width direction of this magnetic layer; forming a nonmagnetic insulating layer so as to cover the magnetic layer and the dishing prevention portion; and planarizing and polishing the magnetic layer, the dishing prevention portion, and the nonmagnetic insulating layer thereafter.

摘要： A thin-film magnetic head provided with at least one MR read head element includes a lower shield layer, an upper shield layer, and an MR layer formed between the lower shield layer and the upper shield layer. A profile of the upper shield layer, appeared at an ABS, has obtuse or rounded upper corners at end edges of the upper shield layer along a track-width direction.
摘要翻译：设置有至少一个MR读取头元件的薄膜磁头包括下屏蔽层，上屏蔽层和形成在下屏蔽层和上屏蔽层之间的MR层。出现在ABS处的上屏蔽层的轮廓在沿着轨道宽度方向的上屏蔽层的端部边缘处具有钝角或圆形的上角。
