ABSTRACT:
A set of coils wind around a magnetic core in a thin film magnetic head. Current supplying circuits are separately connected to the individual coils. The individual coils get shorter in the overall length as compared with the case where a set of coils consist of a single conductor. The impedance of the coils can be reduced. The reduction in the impedance enables the flow of the electric current to be established in a moment within the coils. The magnetic field of a sufficient intensity can be generated in a moment. Magnetization of a sufficient intensity can thus be established on a magnetic recording medium even when the frequency of a signal for recordation gets higher.
