Is a sectional view of the magnetic gap portion in the initial state, and FIG. 2C is a sectional view of the magnetic gap portion after abrasion. In the case of the state of FIG. 2B, no problem occurs when the card slides, but as shown in the state of FIG.
When the shield case portion 8 is worn so as to be convex, spacing is generated between the magnetic card and the magnetic gap portion due to the unevenness of the sliding surface when the magnetic card slides, and unsaturated recording,
When playing a card, there was a risk of problems such as reduced output voltage. Polishing as shown in FIG. 2C is performed when the magnetic core material is soft, when the ratio of the Fe—Ni shield case portion 8 to the area of the magnetic core portion 7 is large, when the width of the counter roller is small, and the counter roller is hard. This is the worn state that is often seen in the case of materials.

A magnetic gap part is formed by inserting a gap material, mold resin is put in, and the magnetic gap part is polished into an arc shape,
The Fe-Ni shield case is removed from the card sliding part so that the contact of the magnetic gap with the magnetic card is always stable even when the magnetic card sliding part is worn.
The magnetic head is characterized in that the card sliding portion is composed of a magnetic core portion and an epoxy resin portion.

The winding 9 is applied to the body in advance. The magnetic core 1 is housed in the magnetic core holding frame 2. The magnetic core 1 and the magnetic core holding frame 2 are previously provided with a gap 6 corresponding to the thickness of the epoxy resin layer, and after the circular arc polishing of the magnetic gap portion 41 [see FIG. Is the sliding surface of the magnetic card. As shown in FIG. 1B, the magnetic core 1
The magnetic gap holding portion 2 of the magnetic core holding frame 2 in which is stored is tightened with two screws 5 in the one direction magnetic core holding frame 2 with the magnetic gap material 4 interposed, and the inside is filled with mold resin from the C direction. To be done. Epoxy resin is deposited on the magnetic core 1 and the magnetic core holding frame 2 at the step 6 in FIG. 1A, and then the magnetic gap portion 41 is formed as shown in FIG.
Is polished into an arc shape up to the magnetic core 1 to obtain a finished product.

As shown in FIG. 1 (e), since the Fe-Ni shield case is removed, the magnetic core 1 is formed on the sliding surface when the magnetic card slides.
With the protrusion, the magnetic card and the magnetic gap are polished into a shape that does not cause spacing. This is because the epoxy resin 3 having a larger wear amount than that of the magnetic core, which is generally a metal, is placed around the magnetic core, so that the epoxy resin 3 is first worn and the magnetic core 1 is projected. This is because
