If a stuck material 24 or an abnormal projection exist on the magnetic recording medium 3, the stuck material 24 brought in contact with the projection 23 is eliminated to evade the MR element 21 from being brought into direct contact with the struck material 24.  Even if the stuck material 24 is not removed, the floating amount of the MR head 2 is raised by an amount equal to the stuck material 24 by using th projection 23, and the MR head is evaded from being brought into contact with the stuck material 24 or the abnormal projection. Thus, heat generated by contact between the MR element and the struck material 24 is prevented and the generation of thermal asperity is evaded.
