PROBLEM TO BE SOLVED: To provide a disk mounting structure capable of reliably preventing polishing powder, etc., from entering a gap between layers of a DVD and effectively suppressing generation, etc., of a radial crack caused by the difference of temperatures between two layers in polishing even when a disk to be polished is the DVD of two-layered structure. SOLUTION: In this disk mounting structure 10 for a disk cleaner where a disk 1 to be polished is placed on a turn table 20 in the state of externally fitting its center hole 2 to a spindle 26 and polishing tools 5A and 5B comprising a buff, etc., are pressed to the surface to be polished 1A of the disk 1 and rotated to polish the surface 1A, an adapter 30 to be internally fitted to the hole 2 is inserted between the hole 2 and the spindle 26. |
