摘要: An optical information recording medium according to the present invention includes at least one layer in which a first dielectric film that contains Cr, O and element (M1) selected from Zr Hf, is provided on changed property reversibly by irradiation of laser beams, second are this order side beams incident. The has Cr atom concentration 6 %, 9 larger than film.
