  We Consider models of thin disks (with and without bulges) in the
Bekenstein-Milgrom formulation of MOND as a modification of Newtonian gravity.
Analytic solutions are found for the full gravitational fields of Kuzmin disks,
and of disk-plus-bulge generalizations of them.
  For all these models a simple algebraic relation between the MOND potential
field and the Newtonian potential holds everywhere outside the disk. We give
exact expressions for the rotation curves for these models. We also find that
the algebraic relation is a very good approximation for exponential disks. The
algebraic relation outside the disk is then extended into the disk to derive an
improved approximation for the MOND rotation curve of disk galaxies that
requires only knowledge of the Newtonian curve and the surface density.
