Abstract
The magnetic head of the present invention is capable of improving heat radiativity and preventing overheat of the magnetic head. The magnetic head comprises: a slider having a disk-side face; an element for reproducing data; a shielding layer; a coil for writing data; magnetic poles; a heat radiating layer for radiating heat generated in the magnetic head; and an insulating layer for electrically insulating the heat radiating layer. The heat radiating layer is provided near the element or the coil without touching the element, the shielding layer, the coil and the magnetic poles. The heat radiating layer is made of a material whose heat conductivity is higher than that of the insulating layer. An end of the heat radiating layer is exposed in the disk-side face of the slider.
