Abstract
An optical disk and a method of fabricating the optical disk capable of improving the signal quality and the productivity are disclosed. The optical disk includes a plurality of reflective layers stacked on a substrate, amorphous layers formed among the reflective layers which include a small amount of oxide therein, a recording layer, formed on the reflective layer, for recording information, and a cover layer formed on the recording layer.
