  Using the CLEO detector at the Cornell Electron-positron Storage Ring, we
have measured the scaled momentum spectra, dsigma/dx_p, and the inclusive
production cross sections of the charm mesons D+, D0, D*+, and D*0 in e+e-
annihilation at about 10.5 GeV center of mass energy, excluding the decay
products of B mesons. The statistical accuracy and momentum resolution are
superior to previous measurements at this energy.
