    Abstract: A thin-film magnetic head includes a lower core layer, a gap layer formed on the lower core layer with a lower pole layer therebetween, an upper pole layer formed on the gap layer, an upper core layer formed on the upper pole layer, and a Gd-defining layer for defining the depth in the height direction of the joint surface between the gap layer and the upper pole layer. The width in the track width direction of the gap layer is smaller than or equal to the width in the track width direction of the upper pole layer when viewed from the surface facing the recording medium. By employing such a thin-film magnetic head, the width in the track width direction of the gap layer can be decreased, and thus track narrowing is achieved.

    Abstract: In a magnetic detection device using a magnetic resistance element, the resistance of a layer having a multi-layer structure can be easily adjusted without causing damages to the layer. A magneto-resistance layer is connected in series to a reference resistance layer, and a magneto-resistance layer is connected in series to a reference resistance layer on a substrate. A voltage is applied between a power supply layer and a grounding layer. A first output conductive layer and the reference resistance layer extend in parallel to each other so that they are partially electrically connected to each other via a connection layer. A second output conductive layer and the reference resistance layer extend in parallel to each other so that they are partially electrically connected to each other via a connection layer. Accordingly, it is possible to adjust the resistance of the reference resistance layers by selecting the respective positions of the connection layers.
