Diamond-like carbon over-coats for optical recording media devices and method thereof |
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 ANGSTROM . 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.
