The atomic entropy squeezing in Raman transition is studied by means of quantum information entropy theory. The influences of the initial parameters of the system on the atomic information entropy squeezing are presented. It is shown that the squeezed component number, depth and squeezed direction of the information entropy squeezing can be controlled by choosing atomic distribution angle, the relative phase between the two-mode field and the different of the average photon number of the two field modes, respectively. It is also shown that quantum information entropy is a remarkable precision measure for the atomic squeezing
