摘要： 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 Al.sub.2 O.sub.3 -TiC as the main constituent thereof and on the flying face of the slider is formed Al.sub.2 O.sub.3 -TiO.sub.2. The flying face exhibits an improved sliding property, while enabling use of the excellent features of Al.sub.2 O.sub.3 -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 Al.sub.2 O.sub.3 -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 Al.sub.2 O.sub.3 -TiO.sub.2 deposited upon the surface of the flying face.

摘要： An improved magnetic head support mechanism intended for causing a magnetic head to float over a magnetic recording medium, comprises a spring member for retaining the magnetic head and a loading beam member provided with flanged portions along both longitudinal sides thereof and connected to the spring member at one end thereof and coupled to a shifting mechanism at the other end thereof and capable of giving the magnetic head an urging force to act on the magnetic recording medium. The loading beam member is penetratingly formed with at least one passing hole which permits the passing therethrough of an air stream generated by the rotational movements of the magnetic recording medium when the magnetic head is floating, so that it is possible to reduce the exciting force acting on the loading beam member and to thereby obtain the stabilized floating of the magnetic head.

摘要： In a thin film magnetic head having a thin film on a substrate to form a magnetic circuit associated with a recording medium, a sliding surface of the substrate opposing the recording medium is made of a material; namely, ZrO.sub.2, having a coefficient of thermal conductivity which is sufficient to carbonize a binder of the recording medium when the magnetic head slides on the recording medium, so that a carbonized material can afford to provide good slidability of the recording medium against the magnetic head and life of the thin film magnetic head and recording medium can be prolonged.
