THERMO-OPTICAL DATA WRITING PROCESS AND DATA MEDIUM FOR PERFORMING THIS PROCESS

摘要

THERMO-OPTICAL DATA WRITING PROCESS AND DATA MEDIUM FOR PERFORMING THIS PROCESS The invention relates to thermo-optical inscription or writing on a data support comprising an organic intermdiate layer (2) covered by a metal layer (3). The invention relates to a writing process consisting of creating in the metal layer 3 a plastic deformation as a result of the gaseous pressure exerted due to the local thermal degradation of intermediate layer 2. Inscription produces a bulge-like impression without perforating the metal layer (3). The invention more particularly applies to the thermo-optical inscription and storage of data on an optically readable support by phase or amplitude contrast. Figure 4.
