Abstract
An inverse type compound thin film magnetic with good dispersion of the heat generated in the magnetoresistance (MR) element, ensuring thermal reliability. In one embodiment, an electromagnetic induction type thin film magnetic head, a magnetoresistance effect type thin film magnetic head, a first protective film, a heat dispersion layer with thermal conductivity higher than the first protective film, and a second protective film are formed in succession on a substrate.
