An object of the present invention is to prevent a spacing between a magnetic head and a writing medium at low temperature from increasing to cause a writing/reading error, and to prevent the magnetic head element protruded by a temperature increase from colliding with small protrusions on a magnetic disk surface, and to prevent damage on the element, and to prevent the occurrence of thermal asperity. In order to attain the object, a magnetic head slider is provided, which includes a magnetic head element supported on a rotating magnetic disk via a gap to write or read information on the magnetic disk, and a heat source for heating the magnetic head element. A magnetic disk device is further provided, which includes a magnetic head slider.
