Abstract

A recording medium suitable for a laser thermal recording is characterized in that a plasma polymerized film of carbon disulfide or an organic monomer containing a metal is used as the recording medium.A method for manufacturing a laser beam-recording medium of this type is characterized by producing an electric discharge in a CS2 or an organic monomer gas while evaporating a metal such as Te so as to form a plasma polymerized film containing the evaporated metal on a predetermined substrate.
