Abstract

PURPOSE:Not to infurence the tips of an iron core by reversed magnetization against a detection area and to increase magnetic head efficiency by sticking a thin non-magnetic material layers and thick high-permiability magnetic material layers on the front and back of the tip portions of an iron core against the advancing direction of the media.
