ABSTRACT:
A film of magnetic recording media is covered with a layer comprising ZrO.sub.2. Advantageously, the ZrO.sub.2 layer inhibits corrosion in the underlying magnetic recording media. The ZrO.sub.2 layer also exhibits desirable mechanical properties, e.g. reduced stiction. In one embodiment of our invention, the ZrO.sub.2 is sputtered onto the magnetic recording media.
