The evolution of the angular momentum and angular velocity of uniformly rotating magnetized white dwarfs (WDs) accreting at a constant rate from a thin disk is examined. Depending on the initial mass of the WD, its field strength, and mass accretion rate, the end result is one of the following cases: (1) the central density of the WD exceeds the critical density for collapse and a rapidly rotating neutron star is formed directly; (2) the WD collapses first to a 'fizzler' and later becomes a neutron star; or (3) the WD attains the maximum angular momentum allowed for its mass (in order to accrete any more mass and collapse the WD must lose angular momentum, but the mechanism by which it might do this is not clear). Unless case (3) can produce collapse, the number of systems that lead to low-field short-period neutron stars, similar to the known msec pulsars, is small.
