摘要： An optical recording medium 10 comprises a substrate 1, first protective layer 2, interfacial layer 3, recording layer 4, second protective layer 5, light absorbing and heat generating layer 6, third protective layer 7, reflection layer 8 and a protective film 9 laminated in order. The light absorbing and heat generating layer 6 is a metal layer or an alloy layer containing more than one element out of Ge, Sn, Pb, Cr, Ti, In, Si, Cd, Se, W, Mo, Zr, Nb, Zn and Hf, so that a reflectivity of the optical recording medium 10 and an optical modulation factor, which is an optical modulation factor in a phase changing state of crystalline or amorphous, in the recording layer 4 can be always maintained in high. Accordingly, a recording sensitivity of the recording layer 4 in the optical recording medium 10 can be increased without deteriorating a characteristic such as reflectivity and jitter.

摘要： A mark having a length nT (n being an integer equal to or greater than 3 and T being a clock period) is formed by modulating irradiation laser power with three values of recording power Pw, erase power Pe, and bias power Pb (Pw Pe > Pb). Constant strength periods of the recording power Pw are set as A t T, A l T, ... , and A m T and constant strength periods of the bias power Pb are set as B t T, B l T, ..., B m T, and CT (C = -1 to 3). The application of laser is divided into pulses in order of A t T, B t T, A l T, E l T, ... , A m T, B m T, and CT (m = (n-k)/2, k=3 (if n is an odd number), or k=4 (if n is an even number)). (Here, the constant strength period A t of the recording power Pw for n=3, D=4 n≥5 (odd number), and n≥6 (even number) is set as A t3 , A t4 , A tod , and A tev , the constant strength period Bt of the bias power Pb for n=3, n=4, n≥5 (odd number), and n≥6 (even number) is set as B t3 , B t4 , B tod , and B tev , and then, At 3 +B t3 = A tod +B tod = A m +B m = 2T and At4+Bt4 = A tev +B tev = 3T).
