ABSTRACT:
A carbon film for protecting a magnetic disk is sputtered in the presence of hydrogen. If a sufficient amount of hydrogen is present in the sputtering chamber, the resulting carbon film will exhibit superior mechanical characteristics, i.e. an enhanced wear resistance during a contact-start-stop or drag test in a disk drive. Sputtering in the presence of hydrogen can be accomplished by either DC or RF magnetron sputtering, or DC or RF diode sputtering.
