PURPOSE:To improve recording performance by forming a viscous film consisting essentially of the polymer of fatty acid series hydrocarbon having a high degree of satn. on a thin film layer and forming further a protective film thereon. CONSTITUTION:The org. viscous film 10 which is easily deformable in follow up to the slight deformation of the recording film generated in parallel with the optical characteristic change arising from the local heating by a laser beam and has tackiness is provided on the recording film 2 and further the protective film 11 which improves the durability of the disk is formed on the film 10. The signal deterioration in the stage of recording information is thus prevented and the information recording medium having high reliability is obtd. |
