摘要：
Disclosed are a thin film magnetic head that has a recoding coil and a method of forming a recording coil can sufficiently achieve a cross-sectional area of the coil and reduce coil resistance. A recording coil of a thin film magnetic head is formed as follows. First, frames, which divide a coil forming area, are formed on the plating base film for forming a coil. Further, the plating base film exposed between the frames is etched, and etching rebounds the plating base film are re-attached to a frame side wall. Then, a nonmagnetic metal layer is formed by plating on the area divided by the frames. Accordingly, the recording coil that has a thickness at both end portions in a coil width direction that is larger than that of a central portion thereof is obtained.

公开了一种具有记录线圈的薄膜磁头，并且形成记录线圈的方法可以充分实现线圈的横截面积并降低线圈电阻。 如下形成薄膜磁头的记录线圈。 首先，在用于形成线圈的电镀基底膜上形成分割线圈形成区域的框架。 此外，蚀刻在框架之间露出的电镀基膜，并且将镀覆基膜的蚀刻反弹重新附着到框架侧壁。 然后，通过电镀在由框架分割的区域上形成非磁性金属层。 因此，获得在线圈宽度方向上的两端部的厚度大于其中央部分的厚度的记录线圈。
