Kind Code:
A1
Abstract:
An information recording medium adapted for the application to an optical reflection or transmission video disk, digital audio disk, etc., in which an information recording layer (12) formed of metal with a low melting point is formed through a light transmission heat insulating material layer (13), on a substrate (11) in such a manner that the thickness of the layer (13) is so selected that the medium exhibits the minimum reflectivity to the information transmitting light due to its interference effect causing the light to be absorbed, thereby recording information at low power.
