PURPOSE: To reduce the power of a recording medium for recording by regulating the total amount of components with ≤about 400 low mol.wt. such as a monomer and an oligomer remaining in a substrate to a specified wt% or more.
CONSTITUTION: The total amount of components with ≤about 400 low mol.wt. present in a substrate is finally regulated to ≥0.8wt%. The components include additives such as a mold releasing agent, a polymn. initiator, a mol.wt. regulator, a stabilizer, a lubricant and a plasticizer, low molecular components remaining in the substrate such as a monomer and an oligomer, and substances stuck to a molded body as the substrate. A vapor-deposited Sb2Se3 layer of 350 thickness is formed as a recording layer 12 on a PMMA substrate 11 of 1.2mm thickness obtd. by injection molding, and on the layer 12, a vapor-deposited Bi2Ti3 layer of 492 thickness is formed as a reflecting layer 13 to obtain an optical information recording medium 14.
