The invention relates to a dynamic gas bearing of a motor spindle comprising a rotating shaft that is received in a housing on gas bearings in the radial and axial direction, said shaft comprising a polygonal mirror in a polygonal room, for radially bearing along the shaft at least one radial gas bearing and for axially bearing a front and a rear gas bearing. The ratio of the bearing gap of the rear axial bearing combined with the bearing gap of the front axial bearing attains at least the value 2.
