Magnetooptical recording alloy

摘要

The present invention relates to a magnetic recording medium for magnetic recording, which has perpendicular magnetic anisotropy. Specifically, the present invention allows a rare earth metal amorphous film of a PrTbCo or PrTbFe alloy to be used as a perpendicular magnetic recording medium without deteriorating its corrosion resistivity, and the present invention provides a perpendicular magnetic recording medium which is more stable against thermal fluctuation and can heighten the density as compared with the conventional crystalline magnetic recording medium. <IMAGE>
