Abstract
Two pairs of, i.e., four, centering shafts are provided so as to move in synchronism with each other in opposite directions that are perpendicular to the pull-in direction of a disc and parallel with the recording surface of the disc. The centering shafts butt the outer periphery of the disc and thereby center it.
