Abstract: PURPOSE:To improve a rewriting speed and preservable stability by utilizing the optical properties between an amorphous phase and a mixed phase where crystals coexist. CONSTITUTION:An inorg. dielectric layer 2 made of SiO2 having 100nm thickness, a recording material layer 3 consisting of (Sb2Te3)80-(Bi2Se3)20 and having 100nm thickness, an inorg. dielectric layer 4 made of SiO2 having 100nm thickness, and an acrylic protective plate 6 having 1.2nm thickness via an adhesive layer consisting of a UV curing resin are successively formed on an acrylic substrate 1 having 1.2mm thickness to constitute the main part of the optical recording medium. The layer 3 is crystallized by a laser beam of 790nm wavelength and is further changed in phase from the crystal phase to the amorphous phase by the laser beam. This layer is further changed in phase to the mixed phase in which the crystals coexist in the amorphous phase, by which the intialization is completed. The layer is then changed in phase from the mixed phase to the amorphous phase by the laser beam, by which the writing of random patterns is executed. The phase change between the amorphous phase and the mixed phase is rapidly progressed in such a manner, by which the rewriting speed is increased and the high stability of the amorphous phase and the excellent preservable stability are obtd.
