摘要：
In a magnetically recording and erasing the magnetic latent image on the magnetic recording medium, the magnetic recording medium includes a base layer, a first magnetic layer in which a repetitive magnetic pattern is in advance formed, and a second magnetic layer on which the magnetic latent image to be formed is thermo-magnetically formed. A method of erasing the magnetic latent image on the second magnetic layer includes the steps of simultaneously applying an external magnetic field and heat to be thermally magnetized layer of a magnetic recording medium.
