Development of Wide Band Recording Materials.

Abstract

This report is the final report of a program to develop hard carbon (diamond-like) coatings as environmentally protective coatings for laser disc optical recording media. Two methods for producing the hard carbon films on the metallic thin film media were studied: plasma CVD by a hydrocarbon gas (PCVD), and direct Carbon Ion Beam Deposition (CIBD). Both methods tended to remove the sensitive media layer before the hard carbon layer could be formed. An additional oxide layer deposited on the metallic media solved this problem. This hard carbon/oxide/metallic media system was successful in resisting degradation due to moisture. Keywords include: Thin films; Coatings; Diamond-like-films; Tellurium; Optical recording media; Magneto-optic media; Terbium iron films; and Magnetic thin films.
