Abstract: A method of fabricating a magnetic head device comprising a slider having a magnetic head element, a suspension structure made of a thin resilient material and having one end supporting the slider and the other end to be attached to another member, and a head IC chip. The head IC chip is mounted on the suspension structure so as to face a magnetic recording disc and at a position spaced from the slider-supporting one end of the suspension structure by an intervening portion of the suspension structure. The position is selected so that the intervening portion is effective to suppress a temperature increase in the head IC chip due to at least thermal conduction through the intervening portion.
