As shown in the first figure, a winding groove 5 is provided on the front surface of a soft magnetic material 3 such as ferrite, and a non-magnetic material 2 is provided on the front surface of this soft magnetic material 3.
A magnetic thin film 1 with high magnetic permeability such as permalloy, amorphous alloy, etc. is sandwiched between a reinforcing member constructed by bonding the reinforcing members and a reinforcing member constructed in the same manner. A coil 8 is provided across the groove 5°5. In addition, 4

ので、巻線工程が煩雑になる欠点がある。Because the magnetic head with this structure has a magnetic thin film 1 with high magnetic permeability sandwiched between two reinforcing members, it is necessary to wind the wire across the winding grooves 5 after the head chip is completed. Therefore, there is a drawback that the winding process becomes complicated.

きる効果を奏する。In the magnetic head of the present invention, as described above, a magnetic thin film 1 with high magnetic permeability is sandwiched between two reinforcing members constructed by bonding a non-magnetic material 2 to the front surface of a magnetic material 3°, and the magnetic thin film 1 of both reinforcing members is 3m
A winding groove 5.5 is provided on the rear surface of each of the 3 m, and the coil 8t is inserted across these winding grooves 5, 5, and a back core is installed on the rear surface of the magnetic body 3° 38 of both reinforcing members. Since the magnetic body 3be is bonded to form the coil 8t, the winding grooves 5, 5 are formed by winding the coil 8t, which has been pre-shaped as shown in FIG. 2(b).
In other words, the coil 8 can be fitted into the main column part 7 and then the magnetic body 3b forming the back core can be joined. There is no need to apply wire, and the winding process can be simplified.
