Abstract
The present invention relates to a thermomagnetic recording apparatus in which a chemical compound material the Curie point of which varies in response to a ratio of chemical combination in chemical compound constituent is utilized as a magnetic material for its magnetic recording medium, and the Curie temperature is set higher than the ambient temperature by a prescribed value on the ratio of chemical combination determined, thereby resulting in printing at a relatively low temperature and precision of printing in a prescribed degree.
