Measurements of inclusive differential cross sections for charged pion and kaon production in $e^{+} e^{-}$ annihilation have been carried out at a center-of-mass energy of $\sqrt{s} = 10.52 GeV$ . The measurements were performed with the Belle detector at the KEKB $e^{+} e^{-}$ collider using a data sample containing $113 \times 10^{6}$ $e^{+} e^{-} \to q \bar{q}$ events, where $q = {u, d, s, c}$ . We present charge-integrated differential cross sections $d σ_{h^{\pm}} / d z$ for $h^{\pm} = {π^{\pm}, K^{\pm}}$ as a function of the relative hadron energy $z = 2 E_{h} / \sqrt{s}$ from 0.2 to 0.98. The combined statistical and systematic uncertainties for $π^{\pm}$ ( $K^{\pm}$ ) are 4% (4%) at $z ~ 0.6$ and 15% (24%) at $z ~ 0.9$ . The cross sections are the first measurements of the $z$ dependence of pion and kaon production for $z > 0.7$ as well as the first precision cross section measurements at a center-of-mass energy far below the $Z^{0}$ resonance used by the experiments at LEP and SLC.
