ABSTRACT:
A bilayer magnetic recording medium having first and second magnetic recording layers separated by a nonmagnetic isolation layer is disclosed. The medium is characterized by a high coercivity, low noise and an improved overwrite. In producing the medium, the second magnetic layer is deposited under sputtering conditions effective to produce a higher coercivity.
