ABSTRACT:
An optical recording medium having at least a recording layer11and a light transmitting layer13formed on a substrate10, in which the recording layer11is 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 layer13is 10 μm to 177 μm in thickness, the relation between absorption coefficient “k” and pyrolysis temperature Tdecof organic material isin-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.
