Abstract

PURPOSE:To simplify a structure of a magnetic head and to enable obtaining of a clear recording, by forming a magnetic latent image by a vertical magnetization recording system. CONSTITUTION:Magnetic heads, being of an electromagnet which is formed such that a coil 4 is wound around a core 3, are densely arranged in a direction of a width of a magnetic layer 1. In the case of black-dot-recording, minute magnetization, which alternately direct upward and downward as shown in arrow marks, generates in the magnetic layer 1 through driving of the coil 4 by means of an alternating current, and a magentic flux generated on the surface of the magnetic layer increases, which results in producing a sharp change in magentic flux density to attract a magnetic toner to a dot recording position. Additionally, a base 2 and an AC source are shown in a drawing.
