    摘要： A magnetoresistive head has a substrate (1) and, on the substrate, a magnetoresistive film (40) for converting a magnetic signal into an electric signal by using magnetoresistance effects and a pair of electrodes (60) for causing a signal detection current to flow through the magnetoresistive film. A pair of first domain wall suppressing layers (30) are arranged at opposite end portions of the magnetoresistive film, respectively, to apply a longitudinal magnetic bias to the magnetoresistive film. A second domain wall suppressing layer (45) is also provided for applying a longitudinal magnetic bias, which is weaker compared with the longitudinal magnetic bias applied by the first domain wall suppressing layers, to the magnetoresistive film (40).

    摘要： A magnetic domain controlling film for controlling the magnetic domain of a magnetoresistive film is formed by a patterning technique on a lower insulating film formed on a lower shield film. The magnetoresistive film is formed on the magnetic domain controlling film for converting a magnetic signal from a magnetic recording medium into an electrical signal using the magnetoresistive effect. A resist pattern is formed by the lift-off method on the magnetoresistive film in such a fashion as to leave a region of the magnetoresistive film corresponding to the tracks of the magnetic recording medium. A magnetoresistive element is formed by ion milling leaving only the portion of the magnetoresistive film corresponding to the tracks. An insulating layer is formed on the resist pattern, on the upper surface region of the lower insulating film other than the portion thereof right under the magnetic domain controlling film reduced in thickness by ion milling, and on the upper surface region of the magnetic domain controlling film other than the portion thereof right under the magnetoresistive film. An electrode film is formed on the insulating layer, after which the resist pattern is removed. The insulating layer is contiguously deposited on the upper surface region formed in a thin layer of the lower insulating film and on a part of the upper surface region formed in a thin layer of the magnetic domain controlling film.

Subsequently, when performing non-consumable electrode arc welding, a penetration width w of a molten pool on the side of the vertical plate after penetrating through the back side of the vertical plate is formed equal to or greater than the vertical plate thickness if a lower vertical plate thickness is the same thickness as an upper plate thickness or thinner than the upper plate thickness, and the penetration width of the molten pool is formed equal to or greater than the upper plate thickness if the lower vertical plate thickness is thicker than the upper plate thickness, thereby forming a penetration shape having a desired welding metal part.
