Abstract

PURPOSE:To join plural magnetic heads easily and accurately, by providing a projected part or a recessed part, which cooperates with another member to constitute a fulcrum, on one of faces of plural magnetic heads facing to each other at least. CONSTITUTION:A rising part 16 having a triangular section is formed in the center in the longitudinal direction on a junction face 12 of one magnetic heads 10 of plural magnetic heads 10 and 11, and a junction face 13 of the other magnetic head 11 is flat. In case that these magnetic heads 10 and 11 are joined into a composite magnetic head, the tip of the rising part 16 of the magnetic head 10 is brought into contact with the junction face 13 of the magnetic head 11, and the gap part between these heads is filled up with an epoxy adhesive 17. Magnetic heads 10 and 11 are moved with the contact part between the rising part 16 and the junction face 13 as the fulcrum and are adjusted to complete the joining. Thus, since the parallel degree of the magnetic gap or the like is adjusted under the stable state, these magnetic heads are joined easily and accurately.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to obtaining a composite layer magnetic head formed by combining a plurality of O1m magnetic heads, each of which has an O1m magnetic head.
At the same time, it is also important to combine the characteristics of each magnetic head and the 41 properties of each magnetic head to the best possible combination.

- In addition, in the composite lid magnetic head, it is OE brass recording and reproducing**
In order to make the best possible results, after raising the head tubes, they are joined together to form a composite lid. ζO field, the magnetic head O tape sliding mwO formation state does not change O'e1 even if the gap and the tape make accurate contact. However, in the case of a multi-purpose head, there are inevitably multiple O gaps. Therefore, the mutual positional relationship of the gear lugs is affected by the tape and the contact.The gap and the tape and the contact are easily damaged. Ru.

= General #c1 [Deteriorates the characteristics of the gold layer magnetic head! ! The most obvious cause of this problem is that since each magnetic head has different and good characteristics, the parallelism R of the gears among the plurality of magnetic heads deviates, and accurate contact between the gap and the tape cannot be made. Furthermore, if the parallelism of the vertices of the Chive sliding video is off, tape running becomes unstable. The former causes azimuth loss, and the latter causes ti7 jima XO^ and spacing loss.

Incidentally, if such factors occur, the magnetic head may become virtually unusable.

Now, conventionally, in a pigeon house in which two magnetic heads are placed, as shown in Fig. 111 of the drawing, the connecting surfaces 3 and 4 of each magnetic head 1.1 are brought into contact with each other, and the gap parallelism between them is adjusted. Check that the tape is parallel to the top of the image, and then connect it with adhesive or the like. However, if the parallelism of the gap and the parallelism of the vertices of the tape sliding motion shift, it is often necessary to move each magnetic head mutually to improve the parallelism. ζO Yang Kai, as a result of the contact surface of each oil air head being lowered, O6 Qin meeting had to be performed to obtain parallelism with 人VHK support 1) & I-shaped blind, making it very unstable 1M
It will be a joint effort. Therefore, the work is difficult and 1k
) It requires a lot of work time. In addition, the magnetic head of the die-cutting type which is coupled to the magnetic head is often rounded with a lack of accuracy, and does not necessarily have a good v'h characteristic.

In particular, the present invention provides a composite FFI magnetic head in which the joining operation can be performed easily and accurately, and the combined magnetic head obtained by combining two or more magnetic heads is O% at the highest. It is 〇.

Below, Figure i1 shows a preferred embodiment of the actual @O configuration. This will be explained in detail.
