Magnetic head having a wear resistant layer substantially comprising Cr2O3 and method of manufacturing such a magnetic head

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 Cr2O3 for f...

Zusammenfassung: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 Cr2O3 for forming a contact face (33) for cooperation with a record carrier. The layer substantially comprising Cr2O3 having a thickness in the range between 10 and 100 nm is preferably provided by reactive RF sputtering.
