PURPOSE:To provide a laser beam recording member which makes repeated recording and erasion possible, prepared by forming on a base sheet a plurality of Te layers each sandwitched between dielectric layers and arranged alternately. CONSTITUTION:A recording member is prepared by laminating at least two layers 2, 4, 6 of dielectric substance (e.g. SiO2) and at least two layers 3, 5 alternately to form a sandwitch structure. |
