ABSTRACT:
A method of thermo-magnetic recording employs a recording medium of a magnetization material disposed on an insulator. An area on the medium is joule-heated via the application of a voltage across contacting electrodes up to a bias point, and a heat pattern is applied in the form of an image to form a magnetic latent image.
