PURPOSE:To produce a thin film of a optical information recording member with favorable reproducibility, by a method wherein a sintered material obtained by heat-treating a material obtained by adding Cu, Zn or the like as a solid solution stabilizer to a Te compound, a Ge compound or the like is vapor-deposited on a base. CONSTITUTION:A starting material containing a Te compound, a Ge compound, an Sn compound and Al and further containing at least one metallic element selected from Cu, Zn, Fe and Ni as a solid solution stabilizer is heat-treated. The resultant sintered material is vapor-deposited on the base to provide a thin film comprising at least Te, O, Ge and Sn, thereby producing the optical information recording member. The amount of the stabilizer added is preferably 5-50wt%. The heat treatment of the starting material may be carried out at 600-720 deg.C, and the vapor deposition may be carried out by resistance heating or electron beam vapor deposition. |
