Abstract
The invention relates to thermo-optic writing on an information support comprising a substrate on which there is deposited an organic sub-layer covered by a metal layer. The invention provides a writing process which consists in creating in the metal layer a plastic deformation due to the thrust exerted by the localized swelling of the sub-layer. The writing produces a relief impression without piercing of said metal layer.
