Inclusive Production of charged D* Mesons in                       
          Photon-Photon Collisions at e+e- centre-of-mass                      
                 energies of 183 and 189 GeV                                   
  
 The inclusive production of charged D* mesons in photon-photon                
 collisions has been measured using the OPAL detector at LEP at                
 e+e- centre-of-mass energies  of 183 and 189 GeV. Direct and                  
 single-resolved events are studied separately. Differential                   
 cross-sections as functions of the D* transverse momentum and                 
 pseudorapidity are presented in the kinematic region                          
 2 GeV < pt_D* < 12 GeV and |eta_D*| < 1.5. They are compared                  
 to next-to-leading order (NLO) perturbative QCD calculations.                 
 The total cross-section for the process e+e- --> e+e- c cbar                  
 where the charm quarks are produced in the collision of two                   
 quasi-real photons is measured to be
