摘要： A merged MR head is formed by sequentially stacking a lower shield, a lower shield gap, a magnetoresistive (MR) element, an upper shield gap, a lower magnetic pole/upper shield, a recording gap layer, a coil, a coil insulating layer, and an upper magnetic pole on a side surface of a trailing edge of a floating slider having an air bearing surface. This merged MR head includes a pedestal which is formed on a portion on the lower magnetic pole/upper shield, including the air bearing surface, to have a width larger than that of the upper magnetic pole. The upper magnetic pole is stacked on the pedestal through the recording gap layer. A sidewall of the pedestal in the vicinity of the air bearing surface has a notch which is obtained by forming a plane where a sidewall of the upper magnetic pole is present. A method of manufacturing this merged MR head is also disclosed.
摘要翻译：合并的MR磁头通过顺序堆叠下屏蔽，下屏蔽间隙，磁阻（MR）元件，上屏蔽间隙，下磁极/上屏蔽，记录间隙层，线圈，线圈绝缘层以及具有空气轴承表面的浮动滑块的后缘的侧表面上的上磁极。该合并MR磁头包括形成在包括空气支承表面的下磁极/上屏蔽件的部分上的基座，其宽度大于上磁极的宽度。上磁极通过记录间隙层堆叠在基座上。在空气轴承表面附近的基座的侧壁具有通过形成存在上磁极的侧壁的平面而获得的凹口。还公开了制造该合并的MR头的方法。
