    • A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

    • A thin-film magnetic head is capable of securing an insulating property and minimizing the projection of a recording element section due to heat expansion. The thin-film magnetic head includes a pair of magnetic layers disposed with a predetermined gap therebetween on a surface facing a recording medium. The layers are connected to each other along an inner part in a height direction from the medium-facing surface. A spiral recording coil is disposed between the pair of magnetic layers and wound around a connecting portion of the pair of magnetic layers. The recording coil includes a dense coil portion formed with a pitch smaller than that of the inner part in the height direction so as to be closer to the medium-facing surface than the connecting portion. An organic insulating layer is locally formed to fill coil gaps of the dense coil portion, and coil gaps other than those of the dense coil portion are filled with an inorganic insulating layer.
    • 薄膜磁头能够确保绝缘性能,并且由于热膨胀使记录元件部分的投影最小化。 薄膜磁头包括在与记录介质相对的表面上以预定间隙设置的一对磁性层。 这些层沿着与介质相对表面在高度方向上的内部部分彼此连接。 螺旋记录线圈设置在一对磁性层之间,并缠绕在一对磁性层的连接部分上。 记录线圈包括致密线圈部分,其形成为具有比内部部分在高度方向上的间距更小的间距,以便比连接部分更靠近中间面。 局部地形成有机绝缘层以填充致密线圈部分的线圈间隙,而不是致密线圈部分的线圈间隙填充有无机绝缘层。

    • 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.
