Abstract: Magnetic head having a head face (5) and comprising a head structure composed of thin layers and provided with a transducing element (E11), in which different materials occurring in different areas are present in the head face. The head face is provided with a first layer (31) of a material which is more sensitive to corrosion than other materials in the head face, and the first layer is provided with a second layer (33) of a wear-resistant material which is more insensitive to corrosion than the material of the first layer. The second layer constitutes a contact face (35) for cooperation with a magnetic tape (7).

Abstract: A magnetic head having a head face (5) and a layer structure with a transducing element (E11) and a transducing gap terminating in the head face. At the area of the transducing gap and at both sides of the transducing gap the head face is coated with a layer (31) substantially comprising Cr.sub.2 O.sub.3 for forming a contact face (33) for cooperation with a record carrier. The layer substantially comprising Cr.sub.2 O.sub.3 having a thickness in the range between 10 and 100 nm is preferably provided by reactive RF sputtering.

Abstract: A method of manufacturing one or more magnetic heads starts from a substrate (11) on which a first magnetic layer (13) is provided. A recess (15) is formed in this layer at the location of a transducing gap to be formed, after which a gap layer (19) is provided on a bounding wall (17) of the recess. Subsequently, the recess is filled with a second magnetic layer (23) and a counterblock (31) is provided on the layers after surface-polishing. Finally, a winding aperture is provided.

Abstract: The invention relates to a soft magnetic multilayer film which comprises a number of crystalline main layers and a number of amorphous secondary layers, the main layer substantially exclusively comprising iron as the magnetic constituent, and the secondary layer comprising mainly iron as the magnetic constituent. Such multilayer films exhibit a relatively low magnetostriction constant which is almost not influenced by temperature treatments. Such films are very suitable for use in magnetic heads.

Abstract: Magnetic head comprising a magnetic core having two core limbs (1,3) formed from a ferrite, which core limbs constitute two core faces located opposite each other, at least one of said core faces having a cladding of a soft-magnetic material having a higher saturation magnetisation than the ferrite, and a non-magnetic transducing gap (11) present between the core faces and having at least one layer of a first metallic material (21) and bonded layers (23) of a second metallic material. The cladding comprises a first cladding layer (15) of an alloy based on Ni-Fe on which a second cladding layer (17) of an amorphous alloy based on Co-Ti and/or Zr and/or Hf-Nb and/or Ta is provided, while the first metallic material, chosen from the group of Mo, Ti, Cr and NiCr, is directly provided on the amorphous alloy of the cladding.
