At the surface facing the recording medium, the upper base of the main magnetic pole layer is wider than the lower base so that the width in the track width direction of the main magnetic pole layer gradually increases with distance from the auxiliary magnetic pole layer. A method for making such a perpendicular magnetic recording head is also disclosed.

The supports of the sensor and base substrates are joined to each other and the plurality of electrically connecting portions of the sensor and base substrates are joined to each other. Furthermore, in each of the sensor and base substrates, either the support or the plurality of electrically connecting portions or both extend to the periphery of the sensor substrate or the base substrate.

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.

Abstract: A manufacturing method of a thin film magnetic head is provided. In the manufacturing method of a thin film magnetic head, an inorganic insulating layer is formed along at least a sidewall surface of each conductor part. A gap of each conductor part is filled by an organic insulating layer. An upper surface of the conductor part, a magnetic pole portion, and a connecting layer are grinded to be planar with an organic insulating layer and an inorganic insulating layer. During an upper surface of each conductor part is grinded, the inorganic insulating layer, which is hard, suppresses a shear drop of each conductor part by grinding.

Abstract: A lower shield layer is formed by being embedded in a first recess formed in an under layer. Accordingly, the distance between the lower shield layer and a slider can be reduced. Also, a second metal layer is formed from above a gap layer covering an electrode extracting layer over above the under layer hindwards therefrom. Accordingly, the second metal layer can be brought closer to the slider side than an upper shield layer. Consequently, the thermal dissipation effects of the thin-film magnetic head can be improved.
