摘要:
The present invention relates to an optical data recording medium comprising a recording layer containing Sb in excess at the eutectic point of Sb 70 Te 30 which undergoes reversible phase change between crystalline state and amorphous state which are different from each other in optical properties, wherein the crystalline state is a hexagonal polycrystal substantially composed of single phase made of M z Ge y (Sb x Te 1-x ) 1-y-z alloy (in which z is from not smaller than 0 to not greater than 0.1; y is from greater than 0 to not greater than 0.3; x is not smaller than 0.8; and M is at least one of In, Ga, Si, Sn, Pb, Pd, Pt, Zn, Au, Ag, Zr, Hf, V, Nb, Ta, Cr, Co, Mo, Mn, Bi, O, N and S). Recording is realized by a recording pulse division scheme with a reduced number of divisions.
