The BD-R write-once type utilizes a recording layer of inorganic material. Since it is unaffected by exposure to light, it boasts outstanding archivability. Previous types of write-once type discs such as the CD-R, DVD-R and others utilized organic dye for their recording layer. The BD-R write-once type is based on a completely new concept for the recording layer utilizing a two-layer structure composed of silicon (Si) and copper alloy (Cu) inorganic materials. When heated by the recording laser beam, these melt and the Si and Cu alloy become a composite forming recording marks. Because the material is inorganic, it is not affected by light, thus realizing a disc with outstandingly high reliability in terms of archivability. (Fig. 6)
