A thin film magnetic head comprises a flying slider and a thin film transducer. The flying slider is formed as a polygonal body having a first face constituting a flying face and a second face normal to the first face, on which second face the thin film magnetic transducer is formed. The flying slider is made of a material containing Al2O3-TiC as the main constituent thereof and on the flying face of the slider is formed Al2O3-TiO2. The flying face exhibits an improved sliding property, while enabling use of the excellent features of Al2O3 -TiC in forming the thin film element as well as in machining the flying slider. The slider can be produced by subjecting the flying face of the slider made of a material containing Al2O3-TiC to a gas phase reaction with an oxygen containing gas. Alternatively, a portion of the flying face can be removed and a layer of Al2O3-TiO2 deposited upon the surface of the flying face.
