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 thin film magnetic head is capable of reducing inductance by shortening a magnetic path, and also preventing a cavity from being formed in a coil insulating layer. The coil insulating layer is deposited on a lower core layer and at the rear of a recording portion, and a coil forming groove is formed in the coil insulating layer. Then, a coil layer is embedded in the coil forming groove. With this arrangement, bulges of the layers from an upper surface of the recording portion can be decreased so as to shorten a magnetic path.

摘要： In a method for making a thin-film magnetic head, a primary insulating layer is formed on a lower core layer. An auxiliary insulating layer is formed on the primary insulating layer. A groove defining a track width is formed on the primary insulating layer. Sloping faces are formed in the auxiliary insulating layer. The sloping faces are symmetrically formed and converge toward the lower core layer in the track width direction. The resulting groove has a width which is smaller than the resolution of a resist layer in a reactive ion etching process.

摘要： A magnetoresistive-effect device includes a multilayer film, hard bias layers arranged on both sides of the multilayer film, and electrode layers respectively deposited on the hard bias layers. The electrode layers are formed, extending over the multilayer film. Under the influence of the hard bias layers arranged on both sides of the multilayer, the multilayer film, forming the magnetoresistive-effect device, has, on the end portions thereof, insensitive regions which exhibit no substantial magnetoresistive effect. The insensitive region merely increases a direct current resistance. By extending the electrode layers over the insensitive regions of the multilayer film, a sense current is effectively flown from the electrode layer into the multilayer film. With a junction area between the electrode layer and the multilayer film increased, the direct current resistance is reduced, while the reproduction characteristics of the device are thus improved.

摘要： The upper face of a lower core layer is planarized by polishing, and a lower magnetic pole layer, a gap layer, and an upper magnetic pole layer are deposited in that order on the lower core layer so that the lower core layer connects to the lower magnetic pole layer. The lower magnetic pole layer, the gap layer, and the upper magnetic pole layer are partly removed using a mask layer, and an insulating layer is deposited on the removed portion to form a main portion and an adjoining portion of a groove. A gap depth Gd is formed in the upper magnetic pole layer, and an back insulating layer is formed on the gap layer in a back region. An upper core layer is formed so as to connect to the upper magnetic pole layer and to partly cover a coil in the magnetic pole end region.

摘要： A magnetoresistive sensor is fabricated as follows. First of all, first antiferromagnetic layers are created on the upper surfaces on both sides of a lower-gap layer, sandwiching a track width on the upper surface of the lower-gap layer. Then, a free magnetic layer, a nonmagnetic electrically conductive layer, a pinned magnetic layer and a second antiferromagnetic layer are stacked on the first antiferromagnetic layers and a portion on the track width one after another in the order the layers are enumerated. Since the free magnetic layer is created after the first antiferromagnetic layer, the free magnetic layer and the first antiferromagnetic layer are adhered to each other with a high degree of reliability. When the direction of magnetization in the free magnetic layer is changed by an external magnetic field, the electrical resistance of the magnetoresistive sensor also changes. The change in electrical resistance is, in turn, used for detecting the external magnetic field. Since the first antiferromagnetic layers put the free magnetic layer in a single-domain state in the X direction, the amount of Barkhausen noise can be reduced.

摘要： A thin film magnetic head includes an upper core layer and a lower core layer which are made of an Fe--M--O alloy, an Fe--M--T--O alloy or an NI--Fe--X alloy so that the upper core layer has a high saturation magnetic flux density, low coercive force and high resistivity, and the lower core layer has a lower saturation magnetic flux density than the upper core layer, low coercive force, high resistivity, and a low magnetostriction constant. Also the lower core layer is formed so that the thickness gradually decreases toward both side ends, and a gap layer can be formed on the lower core layer to have a uniform thickness. Since the lower core layer is formed by sputtering, a material having excellent soft magnetic material can be used, thereby enabling recording at high frequency.

摘要： A magnetoresistive sensor fabricated by creating first antiferromagnetic layers on the upper surfaces of a lower-gap layer, the antiferromagnetic layer having first and second exposed portions separated by a track width formed by the upper surface of the lower-gap layer. Then, a free magnetic layer, a nonmagnetic electrically conductive layer, a pinned magnetic layer and a second antiferromagnetic layer are stacked on the first antiferromagnetic layers and a portion on the track width one after another. Since the free magnetic layer is created after the first antiferromagnetic layer, the free magnetic layer and the first antiferromagnetic layer are adhered to each other with a high degree of reliability. When the direction of magnetization in the free magnetic layer is changed by an external magnetic field, the electrical resistance of the magnetoresistive sensor also changes. The change in electrical resistance is, in turn, used for detecting the external magnetic field. Since the first antiferromagnetic layers put the free magnetic layer in a single-domain state in the X direction, the amount of Barkhausen noise can be reduced.
