Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composite magnetic head, and more particularly to a composite magnetic head in which a plurality of magnetic heads each having their own characteristics are connected and attached.

Generally, in this type of composite magnetic head, separate magnetic heads with their own characteristics are created and then connected in parallel.For example, a structure is adopted in which they are housed in a single case and integrated. has been done.

That is, as shown in Fig. 1, a structure is adopted in which magnetic heads 1 and 2, each having their own characteristics, are housed side by side in a case 3 and integrated. The two magnetic heads 1 and 2 are formed so that the sliding surface of the magnetic recording medium has a predetermined curved shape in order to improve contact between the magnetic recording media.
This results in the formation of a recess 4 between them. The presence of this recess 4 deteriorates the contact state of the magnetic recording medium with the gap between the two magnetic heads 1 and 2.
This causes deterioration of output characteristics.

In general, the biggest cause of deterioration of characteristics is the difference in the parallelism of the gap between magnetic heads 1 and 2, which have different characteristics, and furthermore, the magnetization pattern recorded on the magnetic recording medium is This is due to the fact that running becomes unstable up to the gap where the vehicle is opened.

In an attempt to prevent such characteristic deterioration, a conventional structure has been adopted in which a traveling stabilizer plate 5 is provided to close the space between the two magnetic heads 1 and 2, as shown in FIG.

However, if the running stabilizer 5 is formed into a simple flat plate shape as shown in FIG. It is almost impossible to install the magnetic recording medium because it requires careful adjustment, and the magnetic recording medium runs unstable, causing azimuth loss at high frequencies.

Therefore, as shown in FIG. 2, a structure was proposed in which, for example, two bent portions 5a were formed on the side edges of the running stabilizing plate 5 to make the installation and adjustment as easy as possible. Providing only such a slight bent portion 5a will cause the magnetic head 1,
As a result, positioning is attempted only by contact of the bent portion 5a with any one of the parts 2 and 2, making it extremely difficult to achieve the fine tuning described above, and resulting in the same drawbacks as described above.

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and it is possible to accurately position and attach the travel stabilizer, increase the fixing strength of the travel stabilizer, and improve azimuth loss. The purpose is to provide a composite magnetic head.

In order to achieve the above object, the present invention employs a structure in which mounting legs are provided on the running stabilizing plate and are fitted into grooves formed on the side surfaces of the magnetic head.

Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

FIG. 3 and subsequent figures illustrate an embodiment of the present invention. In each figure, the same parts as in FIGS. 1 and 2 are denoted by the same reference numerals, and the explanation thereof will be omitted.

FIG. 3 and FIG. 4 show a traveling stabilizer plate 5 according to the present invention.
In the example shown in FIG. 3, a long mounting leg 6 is cut and raised from approximately the center of one side edge of the running stabilizing plate 5. In the example shown in FIG. 4, the two mounting legs 6, 6 are cut and raised.

When using the running stabilizer plate 5 having such a structure and attaching it to a composite magnetic head, it is necessary to use two magnetic heads whose apexes on the sliding surface side of the two magnetic heads are parallel to each other. By changing the angle between the mounting legs 6 and the running stabilizer 5, the distance between the running stabilizer 5 and the mounting leg 6 is adjusted so that parallelism similar to that of the sliding surface of the magnetic recording medium can be maintained. The mounting leg 6 may be inserted between the magnetic heads 1 and 2 and fixed using resin or the like. When fixed in this manner, since the mounting legs 6 are long, the fixing strength is reliably increased, and azimuth loss can be reduced to almost zero without peeling or misalignment.

Also, as shown in FIG. 5, of the two magnetic heads 1 and 2, for example, a groove in which the mounting leg 6 of the running stabilizer plate 5 is fitted is formed in the case part of the side surface of one of the magnetic heads 1 on the magnetic head 2 side. 7 is formed and this groove 7 is used for positioning the mounting leg 6, the work of mounting the running stabilizer plate 5 becomes extremely easy.

As is clear from the above description, according to the present invention, in a composite magnetic head in which a plurality of magnetic heads are arranged in parallel and a running stabilizer plate is provided on the sliding surface side between the plurality of magnetic heads, A mounting leg extending substantially perpendicularly to the stabilizing plate is integrally formed on the traveling stabilizing plate, and a groove into which the mounting leg fits is opposed to one of the other magnetic heads of the plurality of magnetic heads. Since we have adopted a structure in which the running stabilizer is attached to the sliding surface between the plurality of magnetic heads via the mounting legs, the inclination angle of the running stabilizer with respect to the sliding surface is based on the mounting legs. Fine adjustment is possible, and azimuth loss can be eliminated by adjusting to maintain parallelism with high accuracy to the top of the medium sliding surface of the magnetic head. Furthermore, since there is a groove on the side surface of the magnetic head into which the mounting leg of the running stabilizing plate is fitted, a plurality of magnetic heads can be installed in parallel in close contact with each other without being obstructed by the mounting leg. Furthermore, since the groove only needs to be provided on the side surface of one magnetic head, processing is easy. Furthermore, since the mounting legs fit into the grooves and are sandwiched between the side surfaces of the plurality of magnetic heads, an excellent effect is obtained in that the running stabilizer plate can be firmly mounted.
