PURPOSE:To radiate generated heat at a high speed, and to prevent damage of a head due to heating, by constituting a thin film magnetic head of a heat pipe. CONSTITUTION:A heat pipe is sealed with a liquid thermal medium in its closed space, and on the inside circumferential surface of the closed space, what is called ''wick'', which has been formed by a very fine linear body is placed. The heated thermal medium is evaporated, and after that, is moved to a low temperature side, is cooled, and the dewed thermal medium is returned to a heating position by a capillary phenomenon generated by existence of said wick, and such circulation is repeated, and radiation is executed very efficiently. On the radiation side end part of a substrate 1 having a heat pipe structure, a radiation fin 4 is formed, and it is constituted so that shifted heat can be radiated quickly. |
