Method for controling the heating elements of a thermal print head

摘要

For recording and erasure of data on a reversibly writable thermal recording material (5) with a thermal print head (2), the heating elements (8) 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 (T1) at which it assumes a colored and/or opaque state. For erasure subsequent to the recording pulse (W), the heating elements (8) are subjected to an energy pulse train (E1).
