The magnetic head has a polished contact zone in the form of a spherical segment corresponding substantially to the arc of contact of a magnetic tape. To obtain a uniform contact pressure even after abrasion of the contact zone, the ends of the latter when viewed in the feeding direction of the tape, transit into shoulders sloping at sharp angle relative to a plane normal to the contact zone. The shoulders are either straight or of a concave contour.
