摘要： An integrated circuit is provided with two output terminals and a mode switch circuit which includes a pair of switch terminals. The mode switch circuit is allowed to switch the output mode between the 1-output mode for outputting the (+) magnetic field detection signal and the (−) magnetic field detection signal from the output terminal, and the 2-output mode for outputting the (+) magnetic field signal from the output terminal as one of the output terminals, and the (−) magnetic field detection signal from the output terminal as the other output terminal in accordance with the shortcircuit state or the non-shortcircuit state between the switch terminals. The switch terminals are exposed on the surface of the device, and the shortcircuit state and the non-shortcircuit state may be externally adjusted.

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.

摘要： 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.

摘要： 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.

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.
