PURPOSE:To improve recording and reproduction and to increase the density of the recording and reproduction by forming a magnetic gap which has specific narrow width and magnetic gap length by using a thin film or thin belt of a ferromagnetic metallic material with large saturated magnetic flux density or a thin film or thin belt of a ferromagnetic material alloy material. CONSTITUTION:A member 18 made of a nonmagnetic material with wear resistance is arranged in contact at the periphery of the thin film or thin belt of the ferromagnetic metallic material exposed in the surface of a magnetic gap part or its periphery or the thin film or thin belt 17 of the ferromagnetic alloy material. Further, the thin film or thin belt 17 contacts widely the main body part of a magnetic core made of the same magnetic ferrite material as the magnetic ferrite material which constitutes a slide part at the prolongation part of the central rail 12 of the slider part 10. This floating type magnetic head, therefore, has its magnetic gap (g) with specific narrow width and magnetic gap length constituted by the part of the thin film or thin belt 17 having large saturated magnetic flux density. Consequently, there is no fringe and no dummy gap is formed, so high-density recording and reproduction are realized.
