。以下、本実’＠を詳しく説明する。The present invention has been developed in view of the above circumstances, and its object is to provide a means for easily manufacturing a magnetic head having nine structures by attaching a soft magnetic block to a soft magnetic thin film. Honji'@ will be explained in detail below.

る。In the figure, 1 is a good soft magnetic thin film inserted into the base 1N5, one end of which is opposed to the m7kie capable medium for recording/reproduction, and 6 is the end [1
End surface Kl on the opposite side of 7! It is a soft magnetic material block that is placed so that it touches the ground. The soft magnetic thin film must be in complete contact with the soft magnetic block! Tiny. This magnetic head has a first
It has almost the same effect as #1 as the magnetic head shown in the figure.

After this, (a) M@tO is added to the substrate 10 while applying pressure so as not to cause a gap between the substrate 10 and the soft magnetic thin film.
Adhere to. ■Next, this % A is cutting thinly, and this III is for cutting the final shape of the head to 1, so it may be omitted.
It is necessary to polish it to a 111tt plane, and to expose the end face of the soft magnetic thin film to the substrate 5 at a distance of 100 degrees. ) Next, the soft magnetic block DVT surface tttc is deposited. After this, cut it like silk to obtain *t*oa air head.
■最後に先端の形状を整える。■Finally, adjust the shape of the tip.
