Patent ID: 6963474

Claim:
A thin film magnetic head comprising a slider, at least one inductive type electromagnetic conversion element and a thermal diffusion film, the inductive type electromagnetic conversion element including a first magnetic film, a second magnetic film, a gap film, a coil film and an insulating film which are supported by the slider, the forefronts of the first and the second magnetic films being opposed via the gap film in the air bearing surface side of the slider, and thereby, constituting a pole portion the first magnetic film being extended backward from the pole portion on the basis of the air bearing surface, the second magnetic film being extended backward from the pole portion with keeping a given space for the first magnetic film, and being joined with the first magnetic film at a backward joining portion, the coil film being embedded in the insulating film, and being wound spirally around the backward joined portion, the thermal diffusion film being made of a metallic film, continued and expanded outside from the coil film, and disposed in the heat transmission path from the coil film toward the slider, which corresponds to a shortest path between the coil film and the slider, so as to radiate Joule heat created in the coil film via the slider.
