Claims
- 1. A magnetic head having a head face and comprising a head structure provided with a transducing gap, said transducing gap terminating in said head face, different materials being present in different areas of the head face, characterized in that the head face is provided at the transducing gap and at both sides thereof with a first layer of a material which is more sensitive to corrosion than said materials of the head face, and the first layer is provided, at the transducing gap and at both sides thereof, with a second layer of a wear-resistant material that is more insensitive to corrosion than the material of the first layer.
- 2. A magnetic head as claimed in claim 1, characterized in that the first layer has a thickness of between 1 nm and 20 nm and the second layer has a thickness of between 10 nm and 100 nm.
- 3. A magnetic head as claimed in claim 1, characterized in that the material of the first layer mainly comprises a metal selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Al, and Zn.
- 4. A magnetic head as claimed in claim 1, characterized in that the material of the second layer is one of the materials selected from the group consisting of chromium oxide, chromium nitride, hafnium nitride, titanium nitride, chromium carbide, titanium carbide, and tungsten carbide, diamond.
- 5. A magnetic head as claimed in claim 2, characterized in that the material of the first layer mainly comprises a metal selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Cr, Al, and Zn.
- 6. A magnetic head as claimed in claim 2, characterized in that the material of the second layer is one of the materials selected from the group consisting of chromium oxide, chromium nitride, hafnium nitride, titanium nitride, chromium carbide, titanium carbide, tungsten carbide and diamond.
- 7. A magnetic head as claimed in claim 3, characterized in that the material of the second layer is one of the materials selected from the group consisting of chromium oxide, chromium nitride, hafnium nitride, titanium nitride, chromium carbide, titanium carbide, tungsten carbide and diamond.
