PROBLEM TO BE SOLVED: To reduce TA(thermal asperity) generated when a disk comes in contact with a head and to enhance the reproduction output of a MR head. SOLUTION: Materials having high thermal diffusivity such as hydrogen containing amorphous carbon, gas phase synthetic diamond, silicon containing amorphous carbon, amorphous AlN and amorphous BeO are applied to each non-magnetic insulating film of a head element and a disk protective film. A projecting protrusion is formed in the vicinity of the head element.
