Abstract:
The present invention provides a magnetic head that can sustain favorable head contact even when magnetic tapes having different thicknesses are used. A magnetic head has a sliding surface coming in contact with a moving magnetic tape. An electromagnetic transducing element is disposed in the sliding surface. First edges are formed at each end of the sliding surface in the direction of movement of the magnetic tape. Second edges are formed in positions extended in the direction of movement of the magnetic tape from each end of the sliding surface and come in contact with the magnetic tape.
