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 is wear resistant and also exhibits reduced static friction. In one embodiment of our invention, an intermediate layer is sputtered onto the media and the ZrO.sub.2 is sputtered onto the intermediate layer. Advantageously, the intermediate layer adheres strongly to both the media and the ZrO.sub.2. We have discovered that by providing the intermediate layer, static and dynamic friction between a read-write head and the disk tends to remain consistently low, and reliability of the disk is enhanced.
