We obtain bounds on the anomalous magnetic and electric dipole moments of the t-quark from a future high-energy and high-luminosity linear electron positron collider, as the CLIC, with polarized and unpolarized electron beams which are powerful tools for determining new physics. We consider the processes gamma e(-) -> (t) over barb gamma(e) (gamma is the Compton backscattering photon) and e(+)e(-)-> e(-)gamma*e(+)->(t) over bar bv(e)e(+) (gamma * is theWeizsacker-Williams photon) as they are one of the most important sources of single top quark production. For systematic uncertainties of delta(sys) - 0% (5%), b-tagging efficiency - 0.8, center-of-mass energy of root s - 3TeV, and integrated luminosity of L = 2ab(-1) the future e(+)e(-) collider may put bounds on the electromagnetic dipole moments (a) over cap (V) and (a) over cap (A) of the top quark of the order of O(10(-2)-10(-1)) at the 2 sigma (3 sigma) level, which are competitive with those recently reported in previous studies at hadron colliders and the ILC.
