Summary:1. Field of the Invention A disc driving apparatus for stabbly driving a disc within a cartridge. In the apparatus, a vertical position of the disc to generate a force by an air pressure difference within the cartridge in the same direction as a force clamping the disc during rotation of the disc. A supporting member for supporting the cartridge or the disc is arranged such that the disc within the cartridge is positioned above the half height of the cartridge, so that a disc vibration is minimized during rotation of the disc to stabbly rotate the disc, thereby assuring a responsibility of recorded and reproduced information.
