Thin film magnetic head including adhesion enhancing interlayers, and upper and lower gap insulative layers having different hydrogen contents and internal stress states
摘要：
A thin film magnetic head includes a magnetoresistive element portion movable over and relative to a magnetic recording medium for reading information stored therein, upper and lower shielding layers disposed with the magnetoresistive element portion therebetween for magnetically shielding the magnetoresistive element portion, and upper and lower gap insulative layers respectively interposed between the upper shielding layer and the magnetoresistive element portion and between the lower shielding layer and the magnetoresistive element portion. Each of the upper and lower gap insulative layers includes a hydrogen-incorporated film. The upper gap insulative layer has an increased hydrogen content and a reduced internal stress relative to the lower gap insulative layer.
摘要（中）：

薄膜磁头包括磁阻元件部分，其可在与用于读取存储在其中的信息相对的磁记录介质上相对移动;上屏蔽层和下屏蔽层设置有用于磁屏蔽磁阻元件部分的磁阻元件部分，以及上下间隙 分别插入在上屏蔽层和磁阻元件部分之间以及下屏蔽层和磁阻元件部分之间的绝缘层。 上下间隔绝缘层中的每一个包括掺入氢的膜。 上间隔绝缘层相对于下间隔绝缘层具有增加的氢含量和降低的内应力。
