摘要： The thin film magnetic head includes a main magnetic pole layer conducting a magnetic flux to the recording medium so that the recording medium an be magnetized in a direction orthogonal to a surface thereof; a return yoke layer disposed on a trailing side of the main magnetic pole layer; an intermediate protective layer partially disposed on a magnetic shield layer; and a thermal expansion suppressing layer having an edge located on the intermediate protective layer and being in contact with the return yoke layer in an area where the intermediate protective layer is not formed. If the thin film magnetic head is affected by ambient temperature environment, the thermal expansion suppressing layer suppresses the shift of the main magnetic pole layer and the return yoke layer toward the air bearing surface. This suppresses thermal protrusion from occurring on the thin film magnetic head due to ambient temperature environment.

摘要： The present invention provides a method of manufacturing a thin film magnetic head, capable of easily manufacturing a thin film magnetic head with high precision, in which a magnetic shield layer is disposed so as to surround a magnetic pole layer from three directions of a medium outflow direction and two side directions. In a magnetic pole formation region surrounded by a first gap layer portion, a magnetic pole layer and a second gap layer portion are formed and the magnetic pole layer is covered with the first and second gap layer portions. After that, a write shield layer is formed on the first and second gap layer portions so as to surround the magnetic pole layer from three directions (a trailing direction and two side directions). Since a gap between the magnetic layer and the write shield layer exerting an influence on recording characteristics is specified on the basis of the thickness of the first gap layer portion, different from the case where the gap is specified on the basis of pattern precision of the photolithography technique, the gap is controlled with high precision.

摘要： A main magnetic pole layer is constructed so as to have a stacking structure in which a lower main magnetic pole layer having relative low saturated magnetic flux density and an exposed surface area is positioned on a leading side, and an upper main magnetic pole layer having relative high saturated magnetic flux density and having an exposed surface area is positioned on a trailing side. The exposed surface of a main magnetic pole layer has a planar shape of a bilaterally-symmetrical inverted trapezoidal shape in which a width of an upper edge is larger than a width of a lower edge and is equal to or larger than a width of the exposed surface of the main magnetic pole layer at an arbitrary intermediate position between the lower edge and the upper edge. In particular, a height at a center position in the exposed surface area in the upper main magnetic pole layer is larger than a height in the exposed surface area in an arbitrary peripheral position around the center point.

摘要： The present invention provides a method of manufacturing a thin film magnetic head in which MR height and neck height can be determined with high precision. A plurality of thin film magnetic head bars are formed so as to include a plurality of thin film magnetic head precursors, a plurality of RLG sensors for reproducing head portions, and a plurality of RLG sensors for recording head portions. While detecting electrical resistance values of resistance films by using the RLG sensors for the reproducing head portions, the thin film magnetic head bar is pre-polished. Electrical resistance values of the resistance films are detected by using both of the RLG sensors for the reproducing head portions and the RLG sensors for the recording head portions and a tilt of a polished surface of the thin film magnetic head bar is adjusted. After that, while detecting the electrical resistance values of the resistance films by using the RLG sensors for the reproducing head portions again, the thin film magnetic head bar is finish-polished, thereby forming an air bearing surface.

摘要： Provided is a thin film magnetic head capable of improving recording performance. The thin film magnetic head comprises a laminate including a main pole layer and an auxiliary pole layer being disposed in a region facing the main pole layer with a non-magnetic layer in between. After magnetic flux generated in a thin film coil is contained in the auxiliary pole layer through the non-magnetic layer, and then is concentrated on a front end neighboring portion of a front end portion in the auxiliary pole layer, the magnetic flux passes through the non-magnetic layer again so as to flow into a front end portion of the main pole layer. A “main magnetic flux incoming route” flowing from a rear end portion to the front end portion in the main pole layer and an “auxiliary magnetic flux incoming route” flowing from the auxiliary pole layer to the front end portion of the main pole layer can be obtained, so an amount of the magnetic flux supplied to a portion of the front end portion of the main pole layer on a trailing side increases. As a sufficient amount of the magnetic flux is supplied to a portion of the front end portion of the main pole layer on the trailing side so that an emitting amount of the magnetic flux increases, thereby a generation intensity and a magnetic field gradient of a perpendicular magnetic field can be obtained.

摘要： Provided are a thin film magnetic head and a method of manufacturing the same, which can quite reduce a pole width with high accuracy while improving overwrite characteristics. A top pole comprises a laminate constituted of an underlayer and a coating layer, which are laminated in order from the side of a write gap layer. A second coupling position of the underlayer (a position where an underlayer front-end portion is coupled to an underlayer rear-end portion) is located closer to an air bearing surface than a first coupling position of the coating layer (a position where an tip portion is coupled to a yoke portion). A first uniform-width distance and a second uniform-width distance can be set independently, thereby enabling reducing the second uniform-width distance within such a range that the accuracy in forming the tip portion can be ensured, while increasing the first uniform-width distance within such a range that the overwrite characteristics can be ensured.

摘要： A method of manufacturing a perpendicular magnetic write head capable of precisely narrowing a side gap is provided. A tip portion having a cross sectional geometry of an inverted trapezoid is formed in an opening portion of a non-magnetic layer and thereafter, the non-magnetic layer is etched with the tip portion as a mask. Thereby, a portion adjacent to the tip portion in a writing track width direction remains and an outermost edge portion of the tip portion in that direction is located on a plane which coincides with an etching face (side face) of the non-magnetic layer. When a gap layer is formed with a vapor phase growth such as a sputtering method to cover the side face of the non-magnetic layer and thereafter a side shield layer is formed adjacently to the tip portion therethrough, a thickness of the gap layer becomes extremely thin and is reproduced precisely. Therefore, the side gap is narrowed with high precision.
