ABSTRACT:
A process of forming magnetic latent images having an improved resolution and using a simple and high-speed mechanism. A magnetic recording body is heated in a pattern of a picture image to be recorded with a thermal pattern input device such as a thermal head array or laser device. The heated magnetic recording body is then brought into contact with a master magnetic body whereby the magnetized pattern on the master magnetic body is thermomagnetically transferred to the magnetic recording body to form a magnetic latent image thereon. The magnetic pattern on the master magnetic body is periodically variable. The master magnetic body has a Curie point equal to or greater than that of the magnetic recording body, preferably at least 50.degree. C. or higher.
