t is the surface area, tb is the surface area, and the core part 2 is made of a magnetic material in the pressure device of the slider part 1 made of a non-flexible material.
The Jal a is fixed by being bath-bonded with glass 3. The core part 2 has a gap 4 provided in a circle perpendicular to the recording medium running direction indicated by the arrow, and a part 1 facing parallel to the direction of the above-mentioned arrow through this gap 4.
core piece 5°6, and a coil (not shown) attached to the core piece 5 or 6? : Sealed. Further, the core hβ2 is provided with an end side 7.8 parallel to the gap 4.

本発明はこのような問題を解決する新しい慣造り浮動式
磁気ヘッドを提供することを目的とするものであり。The object of the present invention is to provide a new conventional floating magnetic head that solves these problems.

A pair of core pieces facing each other are fixed to the slider portion so as to be parallel to each other in a direction perpendicular to the traveling direction of the recording medium. This is a characteristic feature.

Therefore, unlike the conventional structure, the pair of core pieces of the busy core portion are not arranged parallel to the recording medium running direction.

The disk is fixed via a core 12 made of a magnetic material such as Mn--Zn ferrite or an adhesive 13 such as glass. The gear lug 14 is arranged almost perpendicularly to the recording medium traveling direction as shown by the arrow? : A pair of core pieces 15 and 16 facing each other are arranged so as to rotate around each other on the tilting plate @19 that intersects with the above direction at a distance of 01. : Edge 17 when the recording medium runs

Compared to the first embodiment, this embodiment shows a structure in which the core s12 is arranged on a surface 19 opposite to the f+ surface 19 with respect to the recording medium traveling direction. The composition of this pond is the same as the first one.
以上説明したように本発明によれば、コア都の一対のコ
ア片を記録媒体走行方向と交差する方向に沿って配置し
fこので次のような効果が得られる。As explained above, according to the present invention, the pair of core pieces of the core are arranged along the direction intersecting the running direction of the recording medium, and as a result, the following effects can be obtained.
(1)ギャップ14上を通過するic:録媒体は端辺1
7゜18上の少なくとも一方ρりえは18上しか通過し
ないので、形状効果ノイズが減少する。(1) IC passing over gap 14: Recording medium is on edge 1
Since at least one ρ rie on 7°18 passes only on 18, shape effect noise is reduced.
(2) コア都12は一側面のみが接着剤を介してスラ
イダー部に固定されるので、ストレスの影#はほとんど
ない。(2) Since only one side of the core cap 12 is fixed to the slider portion via adhesive, there is almost no stress.
