Abstract. An improvement of the optical method for surface memorization strength study is proposed. We have found that the surface polar angle θ, imposed by the suitable surface coatings, can be used as a convenient element for surface memorization (recording) of oriented smectic C textures. This is a possibility to identify the information, coded in the memorized pictures.
