MAGNETIC RECORDING MEDIUM AND PROCESS FOR PRODUCING THE SAME
A magnetic recording medium comprises a substrate (1), a ferromagnetic thin film (11) formed on the substrate (1), and a protective film (12) formed on the ferromagnetic thin film (11). The interface between said ferromagnetic thin film (11) and said protective film (12) is free of a reaction deposi...

Summary: | A magnetic recording medium comprises a substrate (1), a ferromagnetic thin film (11) formed on the substrate (1), and a protective film (12) formed on the ferromagnetic thin film (11). The interface between said ferromagnetic thin film (11) and said protective film (12) is free of a reaction deposit of elements constituting said ferromagnetic thin film (11) and free from contamination by foreign substances. The ferrogmanetic thin film (11) is made of a Co-based alloy, Fe-based alloy and/or Ni-based alloy. The protective film (12) is made of Ge, and Ge-based alloy or an Ge-based compound. |
