The cosmic-ray muon momentum spectrum and charge ratio up to momenta approx. =10 TeV/c have been measured with high accuracy. The power index of the differential spectrum of parent mesons at production gradually increases with momentum and becomes 2.84 +- 0.03 in the momentum range 0.8 to 10 TeV/c. The charge ratio is almost constant at a value of 1.27 +- 0.02 from 0.1 to 10 TeV/c.
