A non-contact type rewritable thermal label recording method that can be repeatedly used more than 1000 times with little damage to the recording surface of a recording material even when information is recorded and erased repeatedly by a non-contact method. provide. When performing predetermined drawing by irradiating a laser beam focused on a non-contact type rewrite thermal label using an optical scanning device, the optical scanning device is continuously driven without oscillating the laser beam. Only when the locus of the laser beam (virtual laser beam) assumed when the laser beam is oscillated is moving at substantially constant speed, the laser beam is oscillated to scan and draw the laser beam.
