Abstract

Cette invention se rapporte à une technique servant à empêcher l'altération d'une carte ROM magnétique. A cet effet, des signaux magnétiques sont enregistrés sur la carte ROM selon un procédé dans lequel une couche d'enregistrement magnétique est formée par application d'un revêtement magnétique sur la surface d'un substrat, les signaux magnétiques sont inscrits sur la couche d'enregistrement magnétique pendant que celle-ci n'est pas sèche, et les signaux magnétiques inscrits sont fixés par séchage de la couche d'enregistrement immédiatement après l'inscription des signaux magnétiques. Les signaux magnétiques sont les signaux représentant le nombre d'utilisations. Pendant l'inscription des signaux magnétiques alors que la couche d'enregistrement magnétique n'est pas sèche, les signaux magnétiques ne peuvent être ni effacés ni réinscrits. Etant donné que les signaux magnétiques sont les signaux représentant le nombre d'utilisations, cette carte ROM magnétique est particulièrement appropriée pour servir de carte à prépaiement. Par conséquent, cette carte ROM magnétique, qui ne peut être ni altérée ni utilisée frauduleusement, est particulièrement appropriée pour servir de carte à prépaiement. Il est églalement possible de fixer les signaux magnétiques en les enregistrant aux deux extrémités de la couche d'enregistrement magnétique ou de fixer un ou plusieurs signaux magnétiques intermédiaires en plus des signaux magnétiques aux deux extrémités de la couche d'enregistrement magnétique et de ne pas fixer les autres signaux magnétiques.
