摘要： The invention discloses an optical disc comprising a substrate, a multi-layer structure, and a plurality of ribs. The substrate has a first surface and a second surface set opposite to the first surface. The multi-layer structure is formed on the first surface of the substrate and comprises at least one recording layer. The ribs are formed on the second surface of the substrate. The ribs are used for increasing the rigidity of the optical disc, such that a runout of the optical disc can be suppressed while the optical disc is rotated.
