Abstract

An optical disk substrate includes an annular substrate and a protruding portion. The annular substrate has an inner supporting portion and an outer recording portion having a recording surface. The protruding portion overlaying on the supporting portion has a plurality of indentations on its outer periphery, wherein the total thickness of the protruding portion and the supporting portion is greater than the thickness of the recording portion. An optical disk, wherein a paint layer for recording data is coated on the recording surface of the disk substrate, is also disclosed.
