<p>A thermomagnetic recording method is capable of recording information on a layer (101a) of soft magnetic material which has an axis of easy magnetization normal to the surface of the layer (101a) and in which magnetic bubble domains are generated by application of a bias magnetic field (102, 104). Information is recorded by irradiating the layer with pulses of a focused beam (105) so as to form a magnetic bubble domain having a magnetization opposite to a direction of the bias magnetic field (102, 104).</p> |
