Abstract

A compound disc includes a first substrate and a second substrate. In this case, the first substrate has a first surface and a second surface, wherein the first surface has a groove structure of blue-ray disc and deposits a first semi-reflecting layer and a first recording layer. The first semi-reflecting layer is formed on the first surface while the first recording layer is formed on the first semi-reflecting layer. The second substrate has a third surface and a forth surface. The third layer has a groove structure of digital versatile disc and deposits a second recording layer as well as a second semi-reflecting layer. The second semi-reflecting layer is formed on the third layer while the second recording layer is formed on the semi-reflecting layer. And then the second recording layer is bonded to the second surface of the second substrate. The forth surface has a groove structure of compact disc and deposits a reflection layer. Furthermore, this invention also discloses a manufacturing method of the mentioned compound disc.
