Disclosed in Figure 1 is a thermomagnetographic imaging apparatus 10 comprising an imaging medium 12 and thermal write head 14. A pre-magnetizing structure generally indicated by reference character 18 includes a plurality of upper and lower sets 20 and 22 of short magnet segments. The short magnet segments are arranged so that opposing pairs can be selectively rotated independently from the rest of the pairs in the sets. This allows portions of a previously recorded image to be magnetized and to be rewritten for the purpose of editing or annotation.
