The ratio of the cross section for charm-quark pair production in vector-meson-dominant and single-resolved-photonic two-photon processes to that in direct-partonic ones is estimated to be as large as two so that the cross section for D^<*±>production recently measured by TOPAZ Collaboration at TRISTAN may be explained by these two-photon processes and may not necessarily lead to such indication of scalar-top-quark pair production as assumed by the experimentalists.
