Paper Abstract

One of the main storage elements is a memory element including the light-sensitive medium in which usually takes place the optical information recording. The information recording density on recording media is defined in the first place by their resolution which depends on medium homogeneity and degree of defects presence. Among new materials sensitive to light of particular interest are alkaline-earth sulphide films with additives of rare-earth element ions. Such films allow us to record information with multiple reading and rewriting. The information recording on such media takes place due to electron trapping by trap states materials irradiation with 488 nm laser radiation. The reading takes place owing to release of earlier trapped electrons from long-lived states under action of IR laser radiation (the wavelength is of 1064 nm).
