An optical disc-producing sheet, which has an adhesive layerhaving a specific heat capacity after curing of not more than 1.9 J/g·° C. at 80° C. and a protective sheet, is laminated onto an information recording layer(a laminate of a reflecting layer, a dielectric layer, a phase change layerand a dielectric layer') formed on an optical recording medium substrate. According to this optical disc, recorded information can be reproduced accurately even in the case that recording/erasure or reproduction of information has been carried out repeatedly.
