The disks 1 are stacked in five layers. Next, the disk 1 and the spacer 2 are held between the upper holder 3 and the lower holder 4, and the mechanical rotation center of the disk 1 is positioned using a positioning jig (not shown). Thereafter, by screwing together the bolts 5 and nuts 6, the five discs 1 are stably held by the upper retainer 3 and the lower retainer 4, forming what is called a disc back. .
