Open charm production in γγ collisions is studied with data collected at e+e− centre-of-mass energies from 189 GeV to 202 GeV corresponding to a total integrated luminosity of 410 pb−1. The charm cross section σ(γγ→ccX)) is measured for the first time as a function of the two-photon centre-of-mass energy in the interval from 5 GeV to 70 GeV and is compared to NLO QCD calculations
