Abstract
An optical recording disk includes a dye base recording layer, an intermediate layer, and a reflective layer on a substrate in the described order. The reflective layer is composed of one or more metal elements, for example, copper alloy, and the intermediate layer contains a compound of the one metal element or a compound of at least one of the metal elements, for example copper oxide. The intermediate layer minimizes undesirable interactions between the recording and reflective layers.
