Abstract:
An optical disc capable of suppressing vibration during read/write process includes an annular substrate, a coated layer, and a damping layer. The annular substrate includes a supporting portion and a recording portion, and a recording surface corresponding to the recording portion. The coated layer is formed on the recording surface. The damping layer is formed on the coated layer side of the annular substrate for increasing the response time to vibration of the optical disc. A method for fabricating the aforementioned optical disc is also disclosed.
