This will be explained using drawings. As shown in Fig. 8, after applying the Fc-Al-5i alloy magnetic thin film ■ having a high saturation magnetic flux density to the gap forming surfaces of the first core ■ and the second core ■, the gap length is defined. For either method, a non-magnetic film (2) is deposited to a predetermined size. and the fourth
As shown in Figure 0, the first core ■ is made of low melting point glass ■
and a second core (2) are joined to form a magnetic head.

ヘッドを提供するところにある。However, in the above-mentioned conventional technology, since the rear part of the gap is only fixed by the low-melting glass ■, strictly speaking, the boundary ■ between the magnetic Fg film ■ and the non-magnetic film ■ in the gap is only pressed. Since the head is not attached to the bone, its strength is weakened, and it may peel off from this part during machining, or cracks may occur from this part when used after the head is completed, resulting in a decrease in yield and poor durability. I would like to address the problem of being inferior. The present invention is intended to solve these problems, and its purpose is to produce a high-performance magnetic spatula with a magnetic thin film in the gap portion at a high yield. The purpose of the present invention is to provide a magnetic head that can be used in A and has high durability performance.

' Highly saturated magnetism on the core half-core half-cup forming surface! In a magnetic head comprising a magnetic thin film that increases the density,
A thin film of low melting glass is deposited on the magnetic thin film on one of the core halves, a nonmagnetic film defining a gap length is deposited on the low melting glass thin film, and the magnetic thin film is deposited on the nonmagnetic film. After applying the low melting point glass thin film again to G, it is joined to the other half of the core to form an integral piece.

It is made of low melting point glass (2) of about 600'C. When this low melting point glass ■ is melted to combine the first core ■ and the second lower ■, the previous low melting point glass thin film ■ also melts, and the magnetic Ti1J and nonmagnetic open are firmly v: :U will be used. The thickness of this low melting point glass thin film varies depending on the gap length to be obtained, but it is sufficient that it has a thickness of 300 to 800 mm. In addition, the magnetic thin film is applied to only one core (℃)
Using a similar method on a lifting platform, a magnetic head with high TL tube strength and no cracking during the process or during use can be obtained.
