Abstract

The Tellurium (Te) based optical disk requires protection since Te is known to oxidize in the presence of oxygen and humidity. The resulting oxide has substantially different writing and reading properties. Parylene is considered as a passivation agent since it is widely used to protect printed circuit boards, hybrid boards and ferrites. Parylene coatings have excellent chemical resistance, purity gas barrier properties, freedom from pinholes, and high dielectric strength.
