Abstract

LE DOMAINE TECHNIQUE DE L'INVENTION EST L'ENREGISTREMENT D'INFORMATIONS PAR UTILISATION D'UN PRODUIT D'ENREGISTREMENT CAPABLE DE PASSER DE FACON REVERSIBLE DE L'UN A L'AUTRE DE DEUX ETATS PHYSIQUES SOLIDES STABLES ET CONCERNE LES PROCEDES SELON LESQUELS ON FAIT CHAUFFER PASSAGEREMENT UN VOLUME LOCALISE DU PRODUIT AU VOISINAGE DE SA SURFACE DE MANIERE A FAIRE PASSER LE SOLIDE D'UN ETAT A L'AUTRE. LE PROBLEME TECHNIQUE POSE CONSISTE A FOURNIR UN TEL PROCEDE QUI PERMETTE D'OBTENIR DES ELEMENTS D'INFORMATION DONT LA RESTITUTION SOIT AMELIOREE (RAPPORT SIGNAL, BRUIT ELEVE). L'ESSENCE DE LA SOLUTION DE CE PROBLEME RESIDE, PAR LE MOYEN DE L'INVENTION, DANS LE FAIT QUE LES DEUX ETATS CONSIDERES SONT ASSOCIES A DES VOLUMES SPECIFIQUES DIFFERENTS ET EN CE QUE L'ON FAIT CHAUFFER UN VOLUME NETTEMENT DEFINI DU PRODUIT 15, CE VOLUME ETANT SUFFISAMMENT GRAND PAR RAPPORT A L'ETENDUE DE LA SURFACE QUI EST CHAUFFEE POUR QU'ON OBTIENNE SUR LA SURFACE DU PRODUIT 11 UNE ZONE NETTEMENT DEFINIE AYANT UNE COURBURE SUPERFICIELLE MODIFIEE PRESENTANT UN RAPPORT ENTRE LES DIMENSIONS APPARENTES VERTICALE ET TRANSVERSALE D'AU MOINS 1:10. L'UTILISATION PRINCIPALE DE L'INVENTION RESIDE DANS LA REALISATION DE MEMOIRES EFFACABLES ET REUTILISABLES.
