An efficient method is developed which allows the calculation of distributions of the surface density in the equilibrium disk configurations with an isolated point mass at the center corresponding to known distributions of the angular velocity. We demonstrate the existence of the upper limit for the ratio `mass of the galactic disk / mass of the central black hole' which essentially depends on the form of rotation-curves.
