Abstract
The structure of a surface-oxidized Co-Cr film for perpendicular magnetic recording media is investigated by Auger electron spectroscopy. It is found that an oxidized Co-Cr film has a distinct duplex oxide scale on its surface when oxidation is carried out at relatively high temperature (∼400°C). From the outermost surface of the film, a CoO-dominant oxide scale and Cr2O3-dominant oxide scale are formed on the Co-Cr alloy film in order.Keywords
