A disk and a manufacturing method and an optical patterning method thereof are provided. The disk has a recording surface for recording data and an opposite non-recording surface for printing label. The disk at least includes a light-sensitive layer and a thermo-sensitive layer. The light-sensitive layer disposed near the non-recording surface. After receiving laser light, the light-sensitive layer transforms the laser light into thermal energy. The thermo-sensitive layer is disposed near the light-sensitive layer. The color of the thermo-sensitive layer can form an optical pattern after receiving the thermal energy.
