摘要： A main magnetic pole layer is formed on an insulating layer flattened into a high-flatness surface, and a yoke layer having a large film thickness is formed on the main magnetic pole layer independently of the main magnetic pole. The main magnetic pole layer has a front end surface formed in a shape with a width size gradually increasing in a direction of track width as the front end surface departs farther away from an auxiliary magnetic pole layer. A perpendicular magnetic recording head can be provided which can suppress the occurrence of fringing in a recording pattern, and can form the main magnetic pole layer with high pattern accuracy, and can satisfactorily-introduce a recording magnetic field to a fore end of the main magnetic pole layer.

摘要： A perpendicular magnetic recording head includes an auxiliary magnetic pole layer exposed at a surface facing a recording medium, a main magnetic pole layer deposited on the auxiliary magnetic pole layer with an insulating layer therebetween, a coil layer for applying a recording magnetic field to the auxiliary magnetic pole layer and the main magnetic pole layer, and a connecting layer placed on the auxiliary magnetic pole layer toward the back from the surface facing the recording medium. 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.

摘要： In a thin film magnetic head, a face surface faces a recording medium and a front surface of an upper core layer is a curved surface which gradually retreats in a height direction generally perpendicular to the face surface as it approaches both sides thereof, and the thickness of the upper core layer gradually increases in the height direction. It is thus possible to appropriately suppress the occurrence of side fringing, efficiently cause a magnetic flux to flow from the upper core layer to an upper pole layer, and make the thin film magnetic head adaptable to a higher recording density.

摘要： A track width regulating section having a track width, which is smaller than the resolution obtained by the wavelength of the light used for exposure and development of a resist, is formed between a lower core layer and an upper core layer. Since the width of the upper core layer is larger than the track width, magnetic saturation can be effectively reduced. Inclined faces are formed on the upper surface of the lower core layer so as to be inclined in directions away from the track width regulating section, thereby adequately preventing write fringing.

摘要： A magnetic detection device of which an output can be completely switched over with an external magnetic field is formed in a small size. A detection circuit is formed by forming circuit elements such as an active element layer and interconnection layers on a substrate. An insulating layer is formed on the detection circuit, and a flat surface is formed on the resultant surface. A magnetic detection element that detects an external magnetic field by using a magneto-resistance effect and a fixed resistance element, which has the same electric resistance as the magnetic detection element but does not react to the external magnetic field, are formed on the flat surface. Electrode layers and a lead layer are formed on the flat surface, and the lead layer and the interconnection layer are electrically connected to each other via a bump penetrating the insulating layer. The magnetic detection element and the fixed resistance element are formed on the flat surface of the insulating layer, thereby forming a small magnetic detection device.

The support portions include beam portions provided between the movable portion and the anchor portions such that spring portions are provided between the beam portions and each of the movable portion and the anchor portions, the beam portions having a rigidity higher than a rigidity of the spring portions. The movable portion translates in the height direction owing to twisting of the spring portions and displacements in the height direction of distal ends of the beam portions, the movable portion being supported at the distal end.

摘要： By forming a rearmost second coil piece so as to have a larger width in the track-width direction and a larger area than those of coil pieces, heat generated in a thin-film magnetic head can be effectively released to the rearmost coil piece. Thus, a temperature rise in the thin-film magnetic recording head can be further reduced than is possible today, thereby preventing the thin-film magnetic head from protrusion due to its thermal expansion.
