A supporting device for data-storage optical discs which includes a rest plate with which at least one supporting element is arranged to receive an optical disc. The supporting device further includes a vacuum assembly and vacuum connecting through-holes for providing vacuum communication between the supporting element and the vacuum assembly. The supporting element includes a base and a side wall arranged to support the optical disc and defining, with the optical disc itself, a vacuum chamber. The vacuum chamber ensures locking retention of the optical disc on the supporting element, while enabling movement of the rest plate, and further achieves cooling of the disc by an air stream passing through the chamber and spreading over the optical disc surface.
