    • A combination read/write thin film magnetic head includes an upper-core layer and a lower-core layer sandwiching a gap layer for writing data on a recording medium. The head also includes a magnetoresistive sensor layer for reading data from the recording medium. The magnetoresistive sensor layer is sandwiched by a lower-shielding layer and the lower-core layers, which also serves as an upper shielding layer. Each of the layers is arranged in parallel to one another. The width of the upper-core layer defines the width of a recording track. The width of the gap layer is made equal in length to the width of the upper-core layer to reduce magnetic leakage outside the recording track at the gap layer. The lower-core layer includes a prominence and a lower-core body. The prominence is made narrower to reduce magnetic leakage outside the recording track between the upper-core layer and the prominence. The lower-core body has slanted surfaces extending away from the upper-core layer. The slanted surface reduce magnetic leakage outside the recording track between the upper-core layer and the lower-core body.
    • 组合读/写薄膜磁头包括上芯层和下芯层,夹着用于在记录介质上写入数据的间隙层。 头还包括用于从记录介质读取数据的磁阻传感器层。 磁阻传感器层夹在下屏蔽层和下芯层之间,下层也用作上屏蔽层。 每个层彼此平行布置。 上芯层的宽度限定了记录轨道的宽度。 使间隙层的宽度在长度上与上芯层的宽度相等,以减少在间隙层处的记录轨道外部的磁泄漏。 下芯层包括突起和下芯体。 突出部分变窄,以减少上芯层和突起之间的记录轨道外的漏磁。 下芯体具有从上芯层延伸的倾斜表面。 倾斜表面减小了在上芯层和下芯体之间的记录轨道外部的磁泄漏。

    • A method for manufacturing a combination read/write thin film magnetic head comprising the steps of: forming a nonmagnetic material layer on a lower-core layer and forming an upper-core layer having a width smaller than that of the lower-core layer on the nonmagnetic material layer; leaving the section of said nonmagnetic material layer sandwiched between the lower-core layer and the upper-core layer as a gap layer and removing the nonmagnetic material layer not covered by the upper-core layer, said step for removing said nonmagnetic material being performed by an anisotropic plasma etching process using a CF4 based gas; trimming both ends of the facing surfaces, to be in contact with said gap layer, of the lower-core layer so as to equalize the width of the facing surface with the width of the upper-core layer, and forming a prominence above the lower-core layer facing the upper-core layer through the gap layer; and forming grades on both upper surfaces of the lower-core layer extending from the base ends of the prominence in the direction away from the upper-core layer.
