Abstract
An energy computing section computes recording energy when target pixels are mark dots or computes erasing energy when target pixels are space dots. A reading section reads out recording-number information specifying recording times from the magnetic recording portion of a recording medium at the time of recording a visible image. An energy compensating section compensates for the energy, computed by the computing section, based on the recording-number information from the reading section. An image recording/erasing section selectively applies the compensated energy to the recording medium through a thermal head, thereby recording a new visible image over an old one. A counter updates the recording-number information from the reading section. A recording section records the updated recording-number information on the magnetic recording portion of the recording medium as new recording-number information. It is therefore possible to always obtain a stable recorded image regardless of the number of recording/erasing cycles.
