Instead of being mounted on the traditional bed, a revolving disk 2 is supported floating or hovering on an air cushion in a stationary support cup 6, and a motor- driven disk 4 is outfitted with dog elements, which transfer the rotation of the driven disk 4 to the hovering revolving disk 2. Especially when the dog elements are magnets 20, 22 one can have playback without rumbling, for in such a case the revolving disk is entirely without mechanical contact with the remainder of the structure. <IMAGE>
