Optical disc, and production method and reproduction apparatus for optical disc |
摘要 |
An optical disc has a data layer including a data-layer substrate made of a transparent material and a data-layer reflection film formed on an upper side of the data-layer substrate, a display layer including a display-layer substrate having a display pattern and a display-layer reflection film formed on a lower side of the display-layer substrate, and an intermediate layer made of a transparent material provided between an upper side of the data layer and a lower side of the display layer. The data- and display-layer reflection films exhibit specific reflectivity to allow the display pattern to be visible from a lower side of the data-layer substrate through the data-layer reflection film. |
