Abstract
An optical recording medium, comprising: a light transparent substrate, a light absorbing layer disposed on the light transparent substrate, a light reflection layer disposed on the light absorbing layer, and a protection layer disposed on the light reflection layer, wherein a cushion material layer is disposed at least above the light reflection layer by the medium of the protection layer, and a protection plate is disposed on the cushion material layer. In the optical recording medium having the above structure, the protection layer may be prevented from being peeled or separated from the other layer constituting the optical recording medium even when an external force is applied thereto, whereby the light absorbing layer and the light reflection layer are stably protected from such an external force.
