ABSTRACT:
A magnetic head for perpendicular magnetic recording system which assures low write current and high recording reproduction efficiency by using a flat coil and increasing the number of turns of the coil. The flat coil is formed on a substrate and a main pole piece is arranged in the center of the coil and vertically to the surface on which the coil is formed. This magnetic head is suitable particularly for manufacture as a thin film magnetic head.
