Abstract
A recording medium in which a substrate, an inorganic material layer adapted to absorb light and generate heat, a first organic material layer made of an organic matter containing metal, and a second organic material layer adapted to be deformed or removed by heat are successively stacked. A metal salt of an organic acid, or organic metal compound etc. are employed for the first organic material layer. Owing to the presence of this layer, the recording medium exhibits a stability against changes in the ambient temperature.
