An optical disk includes a disk body and a cap body. The disk body has a first surface adapted to be printed thereon, a second surface opposite to the first surface and adapted to store optical data, and a central through hole extending from the first surface through the second surface and confined by an annular hole surface. The disk body further has a cap seat flange that extends radially and inwardly from the hole surface and that is formed with a plurality of mounting holes therethrough. The cap body includes a cap plate disposed in the through hole. The cap plate has a top side adapted to be printed thereon, a bottom side, and a peripheral portion on top of the cap seat flange. The cap body further includes a plurality of hooking arms that extend from the peripheral portion at the bottom side and that extend slidably through the mounting holes.
