A device for rotating inside of a disk player and/or recorder a disk shaped data carrier which takes into account that the rotating disk may be eccentered from an imposed rotation axis. Side moving means allow the rotating disk and the fixing means to which the disk is removably fixed, to move inside said player and/or recorder in a rotation plane substantially perpendicular to an axis of rotation of said fixing means. The rotating disk and the fixing means go into a gyroscopic movement inside the player. A plurality of examples to realize the invention are described.
