Abstract

PURPOSE:To increase the durability and reliability, by clipping the energizing coil with nonmagnetic substance holder from both sides via the side surface high permeability magnetic substance thin film bonded with the main magnetic pole thin film, near the tip of the main magnetic pole thin film opposing to the magnetic recording medium. CONSTITUTION:To the groove 11a for energizing coil 15 and the nonmagnetic holder 11 forming implanted part of the side surface high permeability magnetic member 13 such as Mn-Zn and ferrite, the member 13 is glass-bonded, and the plane over the member 13 and the holder 11 is polished to obtain the same plane. Then, the main magnetic pole 14 is formed by sputtering the magnetic thin film such as permalloy. The energizing coil 15 is given through the groove 11a. The groove 12a with regard to the coil 15 is provided to the 2nd nonmagnetic holder 12 and it is fixed to the said holder 11 by using the epoxy system adhesives 17. In this case, the lead of the coil 15 is connected to the electrode terminal 16 fixed to the bottom of the holder 11. Further, the sliding surface with the magnetic tape 1 is formed to barrel type curved surface for the head.
