The dynamics of holographic recording processes in azo-containing side-chain liquid-crystal polymer films is experimentally studied. The possibility of effective control of optical recording conditions by applying an aligning electric field and also by varying the temperature of the polymer layer is demonstrated. In a polymer film 50 $\mu$m in thickness at a diffraction efficiency of around $\sim$75%, a sensitivity of around $\sim$21 см$^2$/J is attained. High-density recording in the form of a Fourier-transform hologram is effected.
