摘要:
An optical information recording medium on which information can be recorded and reproduced by using a laser beam is provided. The medium includes a substrate with a guide groove and a multilayered metal film including at least a first metal layer, a barrier layer and a second metal layer that are deposited on the substrate in this order, or a single layer metal film including at least a metal layer and a recording layer are deposited on the substrate in this order. The second metal layer and the metal layer of the single layer metal film are a material containing Al and a metal element (an additive) as main components.
