Abstract:
An optical disc includes an annular substrate, a coating layer, a damping layer, and a leveling layer. The annular substrate includes a supporting portion, and a recording portion surrounding the supporting portion, wherein the recording portion has a recording surface located on a first side thereof. For disc clamping and cost saving, the supporting portion is thicker than the recording portion. The coating layer is formed on the recoding surface for recording dada. The damping layer is formed on the coating layer to shorten the response time of the optical disc to vibration. The leveling layer is formed on the side of the annular substrate opposite to the recording surface for leveling the disk deformation caused during fabrication. A method for fabricating the aforementioned optical disc is also disclosed.
