  • Magnetic head slider of ceramic material
    Patent number: 4549238
    Abstract: A magnetic head slider consisting of a mixed ceramic made of aluminum oxide/titanium carbide has on its sliding side adjacent a magnetic record carrier a thin layer from which the titanium carbide component has been removed. The titanium carbide component preferably is removed by preferential reactive ion etching in a CF.sub.4 plasma. The magnetic head slider with its sliding surface thus modified exhibits greatly improved sliding properties compared with sliders of the same material having a non-modified sliding surface.
