ABSTRACT:
An optical phase change media comprises a substrate, an active layer having a crystalline and a liquid state, a dielectric layer and a reflective layer. The active layer is of a thickness which will transmit incident light. The dielectric layer is of a thickness such that light passing through the active layer is reflected by the reflective layer and destructively interferes with the incident light reflected directly off of the active layer, thereby causing the crystalline state of the active layer to absorb more light than the liquid state. The result is that the media experiences reduced temperature during writing.
