Abstract

La présente invention se rapporte à un dispositif d'enregistrement (100) qui acquiert des informations de programmation d'enregistrement qui servent à programmer un enregistrement de programme et qui sont stockées sur un disque laser chargé dans un dispositif de lecture (300), et configure lesdites informations de programmation d'enregistrement comme étant les informations de programmation d'enregistrement du dispositif d'enregistrement. Le dispositif d'enregistrement est pourvu d'une unité d'approbation (350) qui permet des mises à jour des informations de programmation d'enregistrement lorsque le disque laser qui stocke les informations de programmation d'enregistrement, est chargé dans le dispositif de lecture (300), et d'une unité de lecture de disque (330) qui écrit les informations de programmation d'enregistrement mises à jour sur le disque laser susmentionné. Par conséquent, le dispositif d'enregistrement (100) a de meilleures caractéristiques d'utilisation.
