ABSTRACT:
A magnetic recording method and apparatus is disclosed. The magnetic recording method includes forming a magnetic latent image on a recording medium with a scanning recording head so that the magnetic latent image has substantially the same width as that of the recording head, recording the magnetic latent image again with the recording head shifted from its first position by a predetermined width to cause overlapping to form a magnetic latent image with a predetermined width narrower than the width of the recording head and making the narrowed magnetic latent image visible.
