In a temperature-recording method for recording a temperature by means of an electrical circuit of a data storage medium, which electrical circuit is suppliable with energy by means of a signal feedable to the data storage medium, provision is made for a physical variable dependent on the temperature to be recorded by means of the circuit supplied with energy, the physical variable being influenced by a temperature-recording material ( 1, 7 ), preferably a piezoelectric or ferroelectric material, co-operating with the circuit, which material comprises alignable electric or magnetic elementary dipoles ( 3 ), and for which temperature-recording material ( 1, 7 ) a Curie temperature is known, exceeding of which causes the alignment of the elementary dipoles to be lost, and the temperature-recording material ( 1, 7 ) being selected in such a way that its known Curie temperature corresponds to a pre-determined limit temperature.
