Abstract

PURPOSE:To increase the recording and reproducing sensitivity and the S/N, by adhering a separate magnetic thin film at the side surface of a main magnetic pole. CONSTITUTION:Another magnetic thin film 5 is adhered to a thin film at the side surface of a main magnetic pole 1 a little apart from a medium contact surface of the main magnetic pole 1. Through this construction, a volume magnetization of the rear part of the main magnetic pole 1 from the tip of the main magnetic pole 1 is increased and a reverse magnetic field at the tip in the main magnetic pole is made small, allowing to increase the recording and reproduction sensitivity. As an example of execution of this invention, the main magnetic pole 1 is formed with vapor-deposition or sputtering at the side surface of a nonmagnetic base 6, and the magentic thin film 5 is similarly formed further on it.
