Abstract
A magnetic recording medium is formed by disposing on a substrate a magnetic recording layer of a Co-Cr alloy. The durability and the environmental resistance of the magnetic recording medium are improved by forming protective layers including a layer of cobalt oxide and a layer of fluorine-containing resin disposed thereon, on the magnetic layer.
