Abstract

PURPOSE: To enable to use it to narrow space such as small window with semi- double gap construction, by butt joint of the front core laminating U-shaped thin plate of alloy of Al, Mo, Fe of specific composition and the ferrite back core of channel-shape.
CONSTITUTION: The thin plate 0.05W0.1mm thick of alloy consisting of Al 14.4W 15.2wt%, Mo 2W4wt% and Fe remaining percentage, is molded with press into two U-shaped parts and laminated to a given thickness. The groove 5 is formed between the center tips, the front core 2 is formed by inserting and fixing the magnetic substance (Sendust), chip 6 and the spacer 7 at the both sides to the groove 5 to form the front core 2. After polishing the butt joint 8 of the both ends of the U- shaped part, the back core 3 winding 4 is butted and fixed. Finally, the tip front of the core 2 is polished to finish the head 1. The said alloy can easily be pressed, the magnetic flux density is high, wear proof is excellent, and also excellent in the press machining and corrosion proof as the core material. Accordingly, the erase of high coercive magnetic force tape can sufficiently be made.
