摘要： For a tape contact face to be formed in a thin-film magnetic head having at least one transducing element, by removing material, a reference plane (29) corresponding to the tape contact face is detected by means of a plurality of markers (27A-27J) juxtaposed in a layer and extending transversely to the tape contact face, which markers have first end portions (27A1-27J1) pointing in one direction and second, spatially separated end portions (27A2-27J2) pointing in an opposite direction, with the second end portions located at different distances from the reference plane, inclined with respect to the reference plane, and adjoining each other steplessly.
