A magnetic head includes core blocks having a medium sliding surface formed on one surface of the core blocks, the medium sliding surface having a slender convex curved shape formed along a sliding direction of a recording medium from the upstream side of the sliding direction to the downstream side, and the medium sliding surface having a magnetic gap formed thereon, wherein the medium sliding surface is shaped along a longitudinal direction thereof like a circular arc with a radius of curvature R while being shaped along a width direction like a circular arc with a radius of curvature r, which is smaller than the radius of curvature R, so that the radius of curvature r is continuously reduced with closer distance to the downstream end of the recording medium sliding direction from a vicinity of the magnetic gap, so that by employing the above magnetic head, a long life magnetic head with small damage due to foreign material adhesion as well as small abrasion can be provided.
