A magnetic recording apparatus for recording information on a magnetic recording medium. A circuit for generates a recording current pulse train and supplies the pulse train to a magnetic head. The last pulse of the recording current pulse train dampled waveform. A ripple current is superposed on the damped waveform.

Magnetic recording apparatus

A transducer supporting apparatus is provided with a rigid structural support connected to a rigid arm portion and a flexible strucural support provided on the free end of the rigid structural support, the flexible structural support comprising two flexible fingers, a transverse frame connecting the two flexible fingers on the extending side thereof through steps, and a slider mounting portion having a tongue form which extends from this frame and is provided adjacent to the two flexible fingers and a slider loaded with a transducer being junctioned with the slider mounting portion. The flexible fingers are so configurated that the end thereof on the side of the rigid arm portion is brought nearer to the plane formed by the floating surface of the slider than the end thereof on the side of the slider mounting portion.

Transducer supporting apparatus and disk storage unit

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.
