Abstract:
1. A manufacturing method of a thin film magnetic head, the method comprising the processes of: (a) forming a protrusion on a side of a surface facing a recording medium on a first magnetic portion, and a connecting portion, on a height side on the first magnetic portion; (b) forming a coil layer between the protrusion and the connecting portion on the first magnetic portion, through an insulating base layer; (c) forming an inorganic insulating layer along at least a sidewall surface of each conductor part constituting the coil layer; (d) filling a gap between each conductor part with an organic insulating layer; (e) grinding an upper surface of the protrusion, an upper surface of each conductor part, and an upper surface of the connecting portion to a predetermined position with the organic insulating layer and the inorganic insulating layer to expose each upper surface of the protrusion, each conductor part and connecting portion coplanarly; and (f) forming a second magnetic portion from the protrusion to the connecting portion.
