An optical recording medium having at least a recording layer 11 and a light transmitting layer 13 formed on a substrate 10 , in which the recording layer 11 is made of an organic material for absorbing an incident light of wavelength of 360 nm to 460 nm, and inducing physical change or chemical change to vary the refractive index, the light transmitting layer 13 is 10 mum to 177 mum in thickness, the relation between absorption coefficient "k" and pyrolysis temperature T<SUB>dec </SUB>of organic material is <?in-line-formulae description="In-line Formulae" end="lead"?>950(° C.)<(Tdec (° C.)-20)/k<4100° C. (1),<?in-line-formulae description="In-line Formulae" end="tail"?> and the absorption coefficient "k" is k>0.0. |
