ABSTRACT:
An information recording medium including a substrate, an optional intermediate layer arranged on the substrate, and a recording layer arranged on the intermediate layer on the substrate, the recording layer including a low melting metal selected from the group consisting of In, Te, Sn, Pb and Bi and a metal compound selected from a metal sulfide, a metal fluoride and a metal oxide. The recording layer further contains a metal having a high surface tension of not less than 600 dyne/cm within temperatures from its melting point to a temperature higher than the melting point by 300.degree. C., the concentrations of the metal varying along the depth direction of the recording layer in such manner that the concentration of the metal on the side facing the substrate is higher than that of the metal on the opposite side where the metal on the side facing the substrate may be in the form of islands. The intermediate layer includes a compound selected from the group consisting of a chlorinated polyolefin, a polymer material having a thermal decomposition temperature of not higher than 300.degree. C., and an organic compound having a surface energy of not higher than 40 dyne/cm.sup. 2.
