Patent ID: 7626915

Claim:
A phase-change optical recording medium comprising: a substrate, and at least a recording layer consisting of a phase-change material disposed on the substrate, wherein the phase-change material is expressed by the following Equation 1 Sb α Z β Q δEquation 1 where Z represents Sn and one of Sn doped with at least one additive element selected from Bi, Pb and O; Q represents C; α, β and δ each represents an atomic ratio; 0.50≦α≦0.79; 0.10≦β≦0.30; and 0.03≦δ≦0.25, wherein a maximum recording linear velocity V H of the phase-change optical recording medium is 20 m/s to 60 m/s, wherein a range of linear velocity of the phase-change optical recording medium recordable even when the recording linear velocity is continuously changed is 0.3V H to 1.0V H , and wherein jitter is less than 12% and reproduction error is 350 or less when 10 repeated recordings are performed.
