Port, 31-2.144 (1985) is a side view showing a conventional magnetic head for a floppy disk. In Fig. 99, (1) is a slider, (2) is a magnetic core, (3) is a pack core, (4) is a gimbal spring equipped with these, which is made of Bθ-Cu alloy or stainless steel. (5) is an FPC (6) is a conductive adhesive that connects the magnetic core (2), back core (3) and FPC! (5
This is for establishing mutual continuity with 1.
すなわち磁気ヘッドとフレキシブル媒体との接触によシ
、磁気コア（２）には静電気が蓄積され、これがノイズ
の原因となるため、上記の導通によって静電気を除去す
るようになっている。That is, static electricity is accumulated in the magnetic core (2) due to contact between the magnetic head and the flexible medium, which causes noise, so the static electricity is removed by the above-mentioned conduction.

なるという問題点があった。As mentioned above, conventional magnetic heads for floppy disk drives use Bθ-Ou or stainless steel as the gimbal spring material, so special processing such as etching is required to obtain the desired shape, which increases the cost. There was a problem in that it became high.
この発明は上記の問題点を解決するためになされたもの
で、コストの安いフロッピディスク装置用磁気ヘッドを
得ることを目的とする。The present invention was made to solve the above problems, and an object of the present invention is to obtain a magnetic head for a floppy disk device at low cost.
