ABSTRACT:
A method for manufacturing a thin film magnetic head comprises forming a first magnetic core extending from a surface facing a recording medium in a height direction. The method further comprises forming first coil pieces from a first conductive material on the coil insulating underlayer at a side of the surface facing the recording medium with respect to the connecting region, and simultaneously forming a first metal layer from said first conductive material on the first magnetic core in the back region located from the connecting region in the height direction. The method also comprises forming a coil insulating layer for covering the first coil pieces, and forming the second magnetic core above the first magnetic core. The method further comprises forming a toroidal coil layer, forming second coil pieces from a second conductive material on the insulating layer, and connecting the second coil pieces to the respective first coil pieces, and simultaneously with the formation of the second coil pieces, forming a second metal layer.
