Abstract
Is disclosed a thermo-magnetic recording device in which a magnetized latent image is produced on a magnetic layer which is initialized through unidirectional magnetization thereof, in the process of locally heating the magnetic layer. The thermo-magnetic recording device includes: (a) a heat generating roller for heating a local portion of the magnetic layer, through contact of an outer surface of the roller with the local portion of the magnetic layer; and (b) a magnetic-field generating device for generating, at the local portion of the magnetic layer, a magnetic field which has the same N-S direction as that of the unidirectional magnetization, and thereby initializing the magnetic layer.
