PURPOSE: To increase the intensity of reading signals and to make the detecting element hardly sensitive with other noise sources by adding a projection extending toward a carrying surface to the element. CONSTITUTION: The detecting element 18 is provided with the projection 20 integral therewith under a magnetic pole 14. The projection 20 has the length defined as X, i.e., the distance between the end 22 of the detecting element 18 and the end 16 of the projection 20. X must not largely exceeds 1.5μm and the width of the projection 20 is made smaller than the width of the magnetic pole 14. The end of the projection preferably exists at nearly the same height as the height of the carrying surface. The edge of the projection of the detecting element is positioned at the same height as the height of the carrying surface or positioned nearer to the carrying surface, by which the higher data density and data speed are made possible and the crosstalks from the adjacent tracks is lessened.
