| titleOfInvention | Magnetic disk and magnetic disk manufacturing method |
| abstract | Provided is a magnetic disk ( 10 ) for a magnetic recording, which comprises a magnetic layer ( 4 ) for a magnetic recording, a protecting layer ( 5 ) formed over the magnetic layer ( 4 ) for protecting the magnetic layer ( 4 ), and a lubricating layer ( 6 ) formed over the protecting layer ( 5 ). The protecting layer ( 5 ) is a layer composed substantially of carbon, hydrogen and nitrogen. The atomic ratio (N/C) of nitrogen and carbon, which was calculated from the spectral intensities of N1s and C1s detected for a detection angle of 7 degrees of photoelectrons by an angularly resolved X-ray photoelectron spectroscopy, is 0.15 to 0.25. This constitution of the protecting layer ( 5 ) is excellent in wear resistance and sliding characteristics even for a film thickness of 3 nm or less and provides a magnetic disk which can avoid a high fly write trouble or the like. |
