The invention relates to the recording and deleting of data on a reversibly writable thermal recording material (5) using a thermal print head (2). An energy pulse (W) is delivered to the heating elements (8) of the thermal print head for recording, said energy pulse causing the recording material to heat up to a temperature (T1) at which it becomes coloured and/or opaque. For deleting following the recording pulse (W), the heating elements (8) are subjected to an energy pulse strain (E1).
La présente invention concerne l'enregistrement et l'effacement de données sur un matériau à impression thermique réversible (5) au moyen d'une tête d'impression thermique (2). Selon l'invention, pour que s'effectue l'enregistrement, les éléments chauffants (8) de la tête d'impression thermique reçoivent une impulsion d'énergie (W) qui permet de porter le matériau à impression thermique à une température (T1) à laquelle ledit matériau se trouve dans un état coloré et/ou opaque. L'effacement faisant suite à l'impulsion d'impression (W) est réalisé grâce à l'exposition des éléments chauffants (8) à un train d'impulsions d'énergie (E1).
