A magnetic circuit is formed by the magnetic thin film 3.4, but the magnetic thin film 4 made of Co-based amorphous magnetic material is saturated.
OOOG! UJ! ：、"The 1:1 ratio μ・is excellent at about t,ooo, but the hardness Hv - is 500
On the other hand, the magnetic image 63 made of sendust is as low as ~600,
Saturation magnetic flux density 13to is approximately 10 + 00
II:: It is about OG and has an initial magnetic permeability μt of about 700, but it is hard
:: The degree H is high at 600 to 700, and Ferrai 1 and Ceramics 2 have high hardness, so they have excellent wear resistance as a whole and have magnetic properties of 19″f″H1s~-/F

1. As in this example, a magnetic thin film 3.4 is placed on the ceramic 2 facing the ferrite l.
Instead of stacking the wires and welding them with the welding glass 6, as proposed in Japanese Patent Application No. 59-59215, a hollow pipe or the like that matches this shape is fixed to the winding window 7 with the welding glass, and then It is also possible to form a magnetic thin film 4.3 laminated on the magnetic thin film 3, and to fix the seven-layer magnetic film 2 to the magnetic thin film 3 via a welding glass.

The present invention is applied to a magnetic head fixed by 6, and 1
The a-layer film of the magnetic thin film 3.4 is formed on both mutually opposing surfaces of both ferrite blocks 1.1.

益を生む。In this example as well, improvements in magnetic properties and wear resistance were achieved! In addition, the saturation magnetic flux density B1o is determined by the pseudo-gap effect at each boundary between the magnetic film 1li4 made of Co-based amorphous magnetic material>magnetic thin film 3>ferrite 1 made of sendust, for example, when the opposing surface of ferrite 1 becomes magnetic. This has the advantage of being weaker than when only the thin film 4 is formed.
