Abstract: In a perpendicular magnetic recording head including a main magnetic pole layer and a return yoke layer which are laminated with a magnetic gap layer interposed therebetween on a medium-opposing surface, and a pair of side shield layers positioned on both sides in the track width direction of the main magnetic pole layer while interposing a nonmagnetic material layer therebetween, the magnetic gap layer is formed in a partial area in the track width direction bridging the main magnetic pole layer and the pair of side shield layers. The pair of side shield layers are in contact with the return yoke layer in a remaining area where the magnetic gap layer is absent.

Abstract: When a manager uses an input device to input the inspected states of the degrees of soundness of a plurality of objects, a data receiving unit receives them as inspection data. A deterioration characteristic calculating unit calculates the average value of the deterioration characteristics of the objects based on data related to the degrees of soundness of the plurality of objects that is received by the data receiving unit. A heterogeneous parameter calculating unit calculates a heterogeneous parameter for each heterogeneous factor that cannot be observed or is difficult to observe, and causes a variation in the deterioration characteristics. A benchmarking unit evaluates the influence of the heterogeneous factors on the deterioration characteristics based on the heterogeneous parameters, and an output unit outputs the evaluation result.

Abstract: Particularly, there is provided a perpendicular magnetic recording head capable of suppressing PTP and obtaining a stabilized recording ability by improving the shape of the opposed surface of a return yoke layer and a method of manufacturing the same. The shape of the return yoke layer on the opposed surface includes a downside formed linearly parallel to a track width direction (X direction shown in the drawing), a center portion where a protrusion portion having a maximum width T1 larger than a track width Tw by protruding upwardly is formed in a position opposed to a main magnetic pole layer in a film thickness direction (Z direction shown in the drawing), and opposed end portions, having a film thickness smaller than the center portion, that extend on the opposite sides in the track width direction of the center portion. As a result, it is possible to properly obtain both effects such as the improvement of the recording ability and the suppressing of PTP generation.

Abstract: A main magnetic pore layer is formed on an insulating layer flattened into a high-flatness surface, and a yoke layer having a large film thickness is formed under 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.

Abstract: A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

Abstract: A thin film magnetic head is provided, in which the amount of protrusion in the periphery of an element portion can be reduced or a local temperature increase of electrode leads of a heating element can be prevented. The thin film magnetic head includes a playback element disposed between lower and upper shield layers, a recording element laminated on the upper shield layer, a heating element which is disposed below a coil layer and which generates heat to allow the playback element to protrude toward the recording medium side through thermal expansion, and a pair of electrode leads including overlapping regions, which are in contact with rear ends of the heating element and which overlap with the upper shield layer, and heat dissipation regions. Furthermore, connection wiring portions of the pair of electrode leads are disposed in a region sandwiched between the upper shield layer and a magnetic layer.
