ABSTRACT:
An optical recording structure layer has an optical reflecting layer, a phase layer on the reflective layer, an active layer on the phase layer and a matrix layer on the active layer. The phase layer and matrix layer are substantially transparent to radiation. A thin metal layer on the matrix layer has a thickness from 20 to 100 Angstroms to achieve a relatively constant absorption and reflection characteristics for the structure over a broad band of radiation.
