Abstract

PURPOSE: To eliminate the core shift by holding the ring-shaped core to the two holding cases, cutting off the holding cases, polishing the cut surface and then fitting the cut cases to adhere them together again.
CONSTITUTION: Core 5 is wound by coils 6 and 6 to be formed into a unified ring- shaped body. One side part 5a of core 5 is inserted into grooves 1b of holding case 1 and fixed by bonding, and then grooves 2b of holding case 2 are fitted to the other side part 5b. Then opposing surfaces 1a and 2a of cases 1 and 2 are matched together to be bonded via the resin or the like. After this, cases 1 and 2 unified into a body is cut off along surfaces 1a and 2a to obtain two separate cases 1 and 2 again. Cut surface 8 is polished, and gap plates 4 are held between opposing cores 5 cut half. Then cut surfaces 8 and 8 are matched together to be bonded after positioning. Finally, the sliding surfaces of cases 1 and 2 are polished to complete a magnetic head.
