摘 要：
PROBLEM TO BE SOLVED: To provide a thin-film magnetic head for especially suppressing the occurrence of
electromigration of a heating element and making small the temperature dependency of the heating
element.;SOLUTION: The heating
element 20 is structured by laminating a heat conductive layer 21 and high melting material layers 22 and 23. Thus, the electromigration of the heat conductive layer 21 can be suppressed. For
example, when the heat conductive layer 21 is made of CuNi and the high melting material layers 22 and 23 are made of Ru, the temperature dependency of the resistance change ratio of the entire heating element 20 can be appropriately made small because in CuNi and Ru, the temperature dependency of a resistance change ratio is inclined to be opposite.;COPYRIGHT: (C)2007,JPO&INPIT 主权项：
