A centering mechanism for centering the disk recording medium over the spindle of a rotating disk storage system is presented. The invention consists of a centerpiece in the disk having three or more fingers pointing in the direction of insertion and curved away from the center of the disk. As the disk is inserted over a tapered spindle, one side or the other of the fingers will contact the spindle and center the disk as it moves toward the tapered spindle. The bottom edge of the center hole of the disk is rounded to form a stop for the fingers. The fingers bend as the disk is inserted, and this stop ensures that the fingers will not bend too far and break. When the disk is fully inserted, all the fingers around the circumference of the hole are contacting the tapered spindle hub and are also bent back against the stop surface on the disk to provide good centering. As the disk is being moved to its final inserted position, the fingers scrape along the tapered spindle to clean the spindle and provide a clean contact surface between the fingers and the spindle.
