Abstract:
The head slider of a magnetic recording apparatus is currently covered with a diamond like carbon (DLC) film, while the magnetic recording layer of the disk is overcoated with hydrogenated carbon film (HCF). The head materials of DLC film were simulated with diamond, while the disk overcoat layer was simulated by a hydrogenated carbon film coated on glass substrates. Triboelectromagnetic phenomena were investigated in the simulated tribosystem. It was found that the triboelectromagnetic phenomena observed in the simulated tribosystem, and their intensity strongly depend on the hydrogen content in the carbon film. This is because the resistivity of the film greatly increases with the hydrogen content.
