Abstract
A process for manufacturing a recordable optical disk including forming a back rewritable layer and depositing a transparent intercalary layer on the back rewritable layer, and forming a front rewritable layer including a metallic alloy and a cermet dielectric such that the front rewritable layer has a transmission rate greater than or equal to about 45%, and a recordable optical disk including a substrate and an active layer including a cermet, wherein the active layer covers at least one back rewritable layer and the active cermet layer has a transmission rate greater than or equal to about 45%.
