【発明の詳細な説明】
本発明は磁気ヘツドの製造方法に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a magnetic head.
従来、磁気ヘツドの製造方法としては、次のよ
うな方法が一般的であつた。 Conventionally, the following methods have been common as methods for manufacturing magnetic heads.
すなわち、第１図Ａのように薄板状の複数の磁
性体１′を積層したのち、その最上面および最下
面に磁性体１′と同面積の薄板状の非磁性体２′
を、それぞれ磁性体１′の表面全体を覆うように
積層して接着し、第１図Ｂのように所定のコア
５′形状に削成したのち、第１図Ｃのように非磁
性体２′の上からコイル３′を巻回して、磁気ヘツ
ド４′を製造していた。 That is, after laminating a plurality of thin plate-shaped magnetic bodies 1' as shown in FIG.
are laminated and glued so as to cover the entire surface of the magnetic material 1', and are cut into a predetermined core 5' shape as shown in FIG. 1B. A magnetic head 4' was manufactured by winding a coil 3' over the head.
しかしながら、このような製造方法では、上下
両面の非磁性体２′の上から巻回したコイル３′の
巻き高さ分だけ磁気ヘツド４′の厚みが増し、ボ
ビンの内径を大きく取らねばならない等の欠点が
あつた。 However, in this manufacturing method, the thickness of the magnetic head 4' increases by the height of the coil 3' wound from above the non-magnetic material 2' on both the upper and lower surfaces, and the inner diameter of the bobbin must be increased, etc. There were some shortcomings.
また、従来、第２図のように磁性体１″を積層
して所定のコア５″形状に削成したのち、この磁
性体コアの両面に非磁性体２″を部分的なコア形
状に削成して積層し、接着したのち、非磁性体
２″を接着していない部分にコイル３″（図示せ
ず）を巻回するという方法も知られていた。 Conventionally, as shown in Fig. 2, a magnetic material 1" is laminated and cut into a predetermined core 5" shape, and then a non-magnetic material 2" is cut into a partial core shape on both sides of the magnetic core. There is also a known method in which, after laminating and bonding, a coil 3'' (not shown) is wound around the portion where the non-magnetic material 2'' is not bonded.
この方法では、コイル３″部分のふくらみは低
く押えられるものの、積層磁性体１″のコアを形
成後に更に非磁性体２″を部分的コア形状に削成
して積層し、接着しなければならないため、工数
が多くかかるという欠点があつた。 With this method, the bulge in the coil 3'' portion can be kept low, but after forming the core of the laminated magnetic material 1'', the non-magnetic material 2'' must be partially cut into the core shape, laminated, and bonded. Therefore, the disadvantage was that it required a lot of man-hours.
本発明の目的は、上記従来の二つの製造方法の
欠点をいずれも克服し、コイル部分のふくらみを
低く押えてヘツドを小型化するとともに、工数を
も短縮することのできる改善された磁気ヘツドの
製造方法を提供することにある。 The object of the present invention is to provide an improved magnetic head that overcomes both of the drawbacks of the two conventional manufacturing methods mentioned above, reduces the size of the head by keeping the bulge of the coil portion low, and also reduces the number of man-hours. The purpose is to provide a manufacturing method.
以下、図によつて本発明の一実施例を説明す
る。 Hereinafter, one embodiment of the present invention will be described with reference to the drawings.
まず、第３図Ａのように、薄板状の複数の磁性
体１を積層してラミネート磁性体１０を形成した
のち、このラミネート磁性体１０の最上面および
最下面に、各磁性体１よりも面積の小さな薄板状
の非磁性体２をそれぞれ積層して接着する。非磁
性体２は、磁気ヘツドコアの補強になるととも
に、磁気ヘツド内部の他の磁性体（シールド板や
フロントマスク）との磁気的遮断にもなる。 First, as shown in FIG. 3A, a plurality of thin plate-shaped magnetic bodies 1 are laminated to form a laminate magnetic body 10, and then a layer is placed on the uppermost and lowermost surfaces of the laminated magnetic body 10, which is larger than each magnetic body 1. Thin plate-like nonmagnetic bodies 2 with small areas are laminated and bonded. The non-magnetic material 2 not only reinforces the magnetic head core but also acts as a magnetic shield from other magnetic materials (shield plate and front mask) inside the magnetic head.
次に、第３図Ｂのように、これらラミネート磁
性体１０および非磁性体２を所定のコア５形状に
一体的に削成する。 Next, as shown in FIG. 3B, the laminated magnetic body 10 and non-magnetic body 2 are integrally cut into a predetermined shape of the core 5.
なお、量産上は、ラミネート磁性体１０および
非磁性体２が積層・接着されたものからコアの多
数個取りが行なわれるため、たとえば第４図Ａ，
Ｂのように多数個のコア５が削成される。 In addition, in mass production, since a large number of cores are produced from a laminated magnetic material 10 and a non-magnetic material 2 laminated and bonded, for example, as shown in FIG. 4A,
A large number of cores 5 are removed as shown in B.
最後に、第３図Ｃのように、非磁性体２を積層
していない部分のラミネート磁性体１０′にコイ
ル３を巻回することにより、磁気ヘツド４が製造
される。 Finally, as shown in FIG. 3C, the magnetic head 4 is manufactured by winding the coil 3 around the portion of the laminated magnetic material 10' on which the non-magnetic material 2 is not laminated.
以上説明したように、本発明は上記構成からな
るため、次のような効果を奏することができる。 As explained above, since the present invention has the above configuration, it can achieve the following effects.
非磁性体２が各磁性体１よりも面積が小さ
く、ラミネート磁性体１０の最上面および最下
面にそれぞれ部分的にしか積層されないため、
非磁性体２が積層されていない部分のラミネー
ト磁性体１０′にコイル３を巻回することによ
り、コイル３のふくらみを低く押えることがで
きる。したがつて、磁気ヘツド４全体としても
小型化することができる。 Since the non-magnetic material 2 has a smaller area than each magnetic material 1 and is only partially laminated on the top and bottom surfaces of the laminated magnetic material 10,
By winding the coil 3 around the laminated magnetic material 10' in the portion where the non-magnetic material 2 is not laminated, the bulge of the coil 3 can be kept low. Therefore, the magnetic head 4 as a whole can be downsized.
コア５削成時に、すでに非磁性体２をラミネ
ート磁性体１０に積層してあるため、第２図の
ような従来の方法に比べて工数を短縮でき、作
業能率が向上する。 Since the non-magnetic material 2 is already laminated on the laminated magnetic material 10 when cutting the core 5, the number of man-hours can be reduced compared to the conventional method as shown in FIG. 2, and work efficiency is improved.
