Abstract
PURPOSE:To enable the stable maintaining of recorded information and to enhance the sensitivity of recording and erasing by forming a recording layer of an alloy having a specific compsn. CONSTITUTION:A substrate 1 is formed of a material which is transparent and is less deteriorated with age, for example, acrylic resin such as polymethyl methacrylate or glass. The recording layer 2 is formed on this substrate 1. The recording layer 2 is formed of the alloy having the compsn. expressed by the formula (Sb100-xSex)100-yMy, where x, y are respectively is 30<=x<=97, 0<y<=20 ranges by atom.% and M is at least one kind of the element selected from Pb, Sn, In, and Tl. The alloy in this compsn. range can be changed in phase between the crystal state and the amorphous state and is stable in the amorphous state. The information recorded part is thereby stably maintained and the deterioration of the signals is decreased. Since the element expressed by M has the effect of enhancing the sensitivity at the time of the phase change, the sensitivity of recording and erasing is enhanced.
