摘要: An optical information recording medium provided with an layer comprising at least Te, O and M atoms (wherein the is one element selected from a metallic element, metalloid or semiconductor most preferably Pd). The comprises in 40 atom %-60 %, 2 %-25 % Te 15 %-58 thus obtaining preferable property having high C/N ratio small jitter wide power margin reproducing b/d (a of bit length b for spot diameter d).
