Accretion disk-driven magneto-centrigugal winds are one of the leading mechanism for producing bipolar outflows in many astrophysical systems. Previous studies of this mechanism have concentrated either on the disk or on the wind. We show that the structures of the disk and the wind are interdependent, and present the first self-consistent solutions for the wind-disk system. In this initial study, we seek only time-independent, self-similar disk-wind solutions, in view of the great difficulties associated with solving the MHD wind equations in general. The magnetic field inside the disk is assumed to be held in place against accretion matter by outward turbulent diffusion. We show that such a disk-wind system is uniquely determined by the disk thermal and magnetic properties. We find that the wind properties depend very sensitively on the plasma-beta and the magnetic diffusivity of the disk, neither of which are well known. The dependence of the disk structure on these parameters is less sensitive.
