摘要:
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).
摘要:
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.
