A method for forming a magnetic head to solve the curved electrodeposited write gap layer problem by initially fabricating the write gap layer to be wider than the intended final P2 pole tip width. The AlGaInP system laser device is placed to plane side from the centerline of the substrate and the AlGaAs system laser device is placed to the }{overscore }) plane side from the centerline of the substrate when viewed from the main emitting plane }) side of laser light. The gel state is brought about through a crosslinking reaction between the at least one rubber compound composition and the at least one amine resin composition. The front legs 13, the rear legs 14, the center member 10, a center front plate 22, and a center rear plate 23 are placed on and securely weld to the lower plate 18, which has an approximate X shape, in a plan view, and an isosceles trapezoidal shape in a lateral cross-section. The apparatus may further include a cover plate and a base plate.
