Millisecond pulsars are probably 'recycled' old pulsars which have been spun-up through accretion from a binary stellar companion. In a globular cluster such a binary is likely to have formed in a tidally dissipative collision between an old neutron star and a low-mass field star from the cluster. The authors also explore the possibility that accretion from a massive disk is able directly to spin up the neutron star; in this case, however, the predicted number of millisecond pulsars in globular clusters would be ten times the number of bright low-mass X-ray binaries. In the model where the neutron star is spun in a binary the predicted number of millisecond pulsars is significantly smaller. If the millisecond pulsar in M28 has a magnetic moment similar to that of the other three known millisecond pulsars, the epoch of spin-up must have terminated ⪉8×108yr ago.
