    摘要: The invention provides a thermal print head with a protective coating of silicon-doped diamond-like carbon (Si-DLC) which imparts superior wear resistance, and improved lifetime. The Si-DLC is comprised of the elements C, H, Si and possibly O, N and Ar. The highly wear and abrasion-resistant Si-DLC diamond-like carbon coating is deposited by ion-assisted plasma deposition including direct ion beam deposition and capacitive radio frequency plasma deposition, from carbon-containing and silicon-containing precursor gases consisting of hydrocarbon, silane, organosilane, organosilazane and organo-oxysilicon compounds, or mixtures thereof. The resulting Si-DLC coating has the properties of Nanoindentation hardness in the range of approximately 10 to 35 GPa, thickness in the range of approximately 0.5 to 20 micrometers, dynamic friction coefficient of less than approximately 0.2, and a silicon concentration in the range of approximately 5 atomic % to approximately 40 atomic %. Optimum performance is obtained when the Si-DLC coating hardness is in the range of approximately 15 to 35 GPa, preferably in the range of about 15 GPa to about 19 GPa, and the Si-DLC layer thickness is in the range of approximately 2 micrometers to approximately 10 micrometers, dynamic friction coefficient of less than approximately 0.15, and a silicon concentration in the range of approximately 10 atomic % to 30 atomic %, preferably in the range of about 15 atomic percent to about 24 atomic percent.

    摘要: A method is provided for manufacturing a diamond-like carbon (DLC) coated optical phase-change recording medium for use with near-field optical head devices and which exhibits superior wear resistance and improved lifetime. According to the method, the surface of a composite optical phase-change media structure deposited onto a substrate is subjected to ion beam deposition of a DLC over-coat to a thickness of no greater than about 450 .ANG.. Preferably the DLC is ion beam deposited onto the phase-change recording layer at the surface of the medium structure or onto a germanium-containing adhesion-promoting interlayer to achieve the desired adhesion of the DLC to the surface of the medium structure.
