Abstract

PURPOSE:To easily manufacture a device, to elevate its recording efficiency, and to increase its track density, by forming a thin film magnetic pole constituting an auxiliary magnetic pole on a substrate, and forming it in one body with a coil formed separately. CONSTITUTION:A main magnetic pole 3 and an auxiliary magnetic pole 4 are installed so as to place a magnetic recording medium 1 between them, a signal current is made to flow to an energizing coil 7 of the auxiliary magnetic pole corresponding to each track, and is recording in a running magnetic recording medium 1. As for the main magnetic pole 3, a high permeability magnetic film is formed on a nonmagnetic substrate 5' by a sputtering method. As for the auxiliary magnetic pole 4, an auxiliary magnetic pole pattern 6 to each track is formed, and after that, in accordance with this pattern, a nonmagnetic substrate 5 is cut and plural arms 5a are formed. To the arm 5a on which the pattern 6 has been formed, the energizing coil 7 which has wound a winding around a bobbin formed by a nonmagnetic material is fitted in the direction as indicated with an arrow B.
