Title: Innovations of Jean Cornet in Thermo-Optic Writing Processes

Introduction

Jean Cornet is a notable inventor based in Paris, France, recognized for his contributions to thermo-optic writing technologies. With a total of 10 patents to his name, Cornet has made significant advancements in the field of data storage and inscription processes.

Latest Patents

Among his latest patents, Cornet has developed a thermo-optic information writing process. This invention relates to thermo-optic writing on an information support that includes a substrate with an organic sub-layer covered by a metal layer. The process involves creating a plastic deformation in the metal layer due to the localized swelling of the sub-layer, resulting in a relief impression without piercing the metal layer. Another significant patent is the thermo-optical data writing process, which also involves an organic intermediate layer covered by a metal layer. This process creates a plastic deformation in the metal layer as a result of gaseous pressure from the local thermal degradation of the intermediate layer, producing a bulge-like impression without perforating the metal layer. These inventions are particularly applicable to the thermo-optical inscription and storage of data on optically readable supports.

Career Highlights

Cornet has been associated with Thomson-CSF, a prominent company in the field of electronics and telecommunications. His work has contributed to the advancement of technologies that enhance data storage and retrieval processes.

Collaborations
