ChemInform Abstract
The overwriting characteristics of a phase-change-type erasable optical recording disk strongly depend on the properties of the protective layer. The effect of adhesion strength and residual stress is investigated. As revealed from application of amorphous SiN:H films by electron cyclotron resonance-PCVD and both S3N4 and ZnS films by magnetron sputtering on a GeSbTe recording layer the residual stress does not play an important role in improving repeatability.
