    • A thin film magnetic head comprises a magnetic yoke piece exposed at a medium-opposed surface adjacent a gap layer. A magnetic yoke layer is connected to the magnetic yoke piece at a position retracting from the medium-opposed surface. The tip end of the magnetic yoke layer is exposed at the medium-opposed surface. A non-magnetic layer is interposed between the tip end of the magnetic yoke layer and the magnetic yoke piece at the medium-opposed surface. The non-magnetic layer serves to space the tip end of the magnetic yoke layer away from the other magnetic yoke layer which is separated by the magnetic yoke piece and a gap layer, for example, from the magnetic yoke layer. It is possible to reduce a magnetic field directed to the other magnetic yoke layer from the edges of the magnetic yoke layer protruding in the lateral direction of a data track. Such magnetic fields from the magnetic yoke layer hardly induce magnetic reversal on a magnetic recording medium such as a magnetic recording disk or tape.
    • 薄膜磁头包括在与间隙层相邻的介质相对表面处暴露的磁轭。 磁轭层在与介质相对表面缩回的位置处连接到磁轭件。 磁轭层的前端在介质相对表面露出。 非磁性层位于中间相对表面处的磁轭层的末端和磁轭之间。 非磁性层用于将磁轭层的前端远离由磁轭片隔开的另一磁轭层和例如磁轭层的间隙层。 可以从在数据轨道的横向方向上突出的磁轭层的边缘减小指向另一磁轭层的磁场。 来自磁轭层的这种磁场几乎不会在诸如磁记录盘或磁带的磁记录介质上引起磁反转。
