For recording and erasure of data on a reversibly writable thermal recording material ( ) with a thermal print head ( ), the heating elements ( ) of the thermal print head for recording are subjected to an energy pulse (W) which causes the recording material to be heated to a temperature (T ) at which it assumes a colored and/or opaque state. For erasure subsequent to the recording pulse (W), the heating elements ( ) are subjected to an energy pulse train (E ).
