| abstract | (57) [Abstract] [Purpose] Even at a thickness of 500 A or less, it has extremely high hardness, excellent adhesion, wear resistance, and lubricity, and is of a practical level that can withstand the requirements of high-density recording technology. Provide a high magnetic disk protective film. [Structure] A silicon coating is provided on the magnetic disk substrate, Next, a hard amorphous carbon protective film containing hydrogen is provided on the silicon coating, and an amorphous carbon film containing hydrogen, boron and nitrogen is further provided on the surface of the hard amorphous carbon film. , Excellent adhesion between magnetic disk substrate and protective film by silicon coating, excellent wear resistance by hard amorphous carbon film, and excellent lubricity by amorphous carbon film containing hydrogen, boron and nitrogen. Combined, 500 Even with a thickness of A or less, it is possible to form a very uniform and excellent magnetic disk protective film. |
