本発明はデータ、又は画像の記録再生に使用する垂直磁
気記録装置の磁気記録用ヘッド、並びにその製造方法に
関する。DETAILED DESCRIPTION OF THE INVENTION A2.Object of the Invention [Field of Industrial Application] The present invention relates to a magnetic recording head for a perpendicular magnetic recording device used for recording and reproducing data or images, and a method for manufacturing the same.
従来高密度磁気記録を行う場合、磁気記録媒体（以下磁
気媒体と称す）に磁気ヘッドとの相対移行方向に沿う方
向の磁化によって記録する所謂長手磁気記録によるより
も、磁気媒体の厚さ方向に磁化する所謂垂直磁気記録に
よる方が有利であることが知られている。Conventionally, when performing high-density magnetic recording, recording is performed on a magnetic recording medium (hereinafter referred to as magnetic medium) in the thickness direction of the magnetic medium, rather than by so-called longitudinal magnetic recording, in which recording is performed by magnetization in the direction along the relative migration direction with respect to the magnetic head. It is known that so-called perpendicular magnetic recording using magnetization is more advantageous.
これは長手磁気記録では磁気記録の長さが短くなるほど
自己減磁作用の影響が大きくなるのに対し、垂直磁気記
録では磁気記録密度が高くなる程磁気記録層内の自己減
磁作用が小さくなる性質をもつことに因るものである。This is because in longitudinal magnetic recording, the shorter the magnetic recording length, the greater the effect of self-demagnetization, whereas in perpendicular magnetic recording, the higher the magnetic recording density, the smaller the self-demagnetization effect within the magnetic recording layer. This is due to the fact that it has certain characteristics.

励磁型単極磁気ヘッドがある。Various types of magnetic heads have been proposed for perpendicular magnetic recording, but in order to achieve ideal magnetization perpendicular to the medium surface of the magnetic medium in perpendicular magnetic recording, the magnetic head The magnetic field generated from the main magnetic pole must be perpendicular to the magnetic medium. As such a magnetic head, there has conventionally been a main pole excitation type unipolar magnetic head as shown in FIG.

ドを構成していた。As shown in Fig. 5, a slider 11 made of zirconia (ZrO□) is made of Ni-Zn with U-shaped grooves formed at equal intervals.
A soft magnetic block 12 made of ferrite is bonded with glass having a softening temperature of 800°C to form a composite block, and then the composite block is made perpendicular to the surface of the slider 11 along C-D parallel to the groove direction shown by the two-dot chain line. Cut, and then C+-D in the same way
+, Cut the composite block into small pieces at equal intervals C2-D2. The side surfaces of the cut surfaces of each of the small pieces of the cut composite block were polished, and the polished surfaces were coated with soft magnetic materials that would become the main magnetic pole 13, including 86.8% Co, 3.6% Zr, and N.
After forming an amorphous magnetic film with b of 9.6% to a desired thickness, e.g. 0.2 μm, by sputtering or the like, etching it to a desired track width dimension, e.g. 60 μm, and then cutting it as shown in FIG. The cut and polished surfaces of the other composite block were brought together so as to sandwich the main pole 13, and glass bonding was performed using a lath with a low softening temperature of about 350°C. - At F2, cut perpendicularly to the sliders lla and 11b, and process the sliders lla and 11b, which will become the sliding surfaces, into a spherical surface to form the auxiliary magnetic pole 12.
A wire was wound in the winding window formed by the U-shaped grooves a and 12b, thereby constructing a main pole excitation type single pole magnetic head shown in FIG. 7.
以上に示す主磁極励磁型単磁極磁気ヘッドの巻線５１は
主磁極部３ｂを挟んで、かつスライダ１１ａ。The winding 51 of the main pole excitation type single pole magnetic head shown above is connected to the slider 11a with the main pole part 3b in between.

いため磁気ヘッドとしての記録再生効率が悪い等の欠点
があった。The efficiency of the winding work is poor because the thin wire is passed through a small window 6 partitioned by the lower end of the flb, and the magnetic flux from the magnetic medium is reduced because the wire cannot be wound to the tip of the main pole. The magnetic head is attenuated by the time it interlinks with the winding of the main pole, and since it is not possible to provide an auxiliary pole in the width direction of the main pole, there are drawbacks such as poor recording and reproducing efficiency as a magnetic head.

ーンバス部を形成出来ないため磁気記録信号を読み取る
ための再生効率が悪いなどの欠点があった。The winding of conventional single-pole heads with main pole excitation involves toroidal winding in the windows provided on both sides of the main pole, making it difficult to mass-produce.
Furthermore, since the structure does not allow winding around the main pole in contact with the magnetic medium, the magnetic flux from the magnetic medium is attenuated by the time it interlinks with the winding, causing a return bus of magnetic flux in the direction of the track. Since it cannot be formed, there are drawbacks such as poor reproduction efficiency for reading magnetic recording signals.

は向上する。Configuration of the Invention [Means for Solving the Problems] In order to achieve the above object, the present invention forms a composite block plate by joining a non-magnetic plate serving as a slider and a soft magnetic block serving as an auxiliary magnetic pole with glass. The first step is to cut the composite block plate perpendicularly to the slider surface, and the second step is to flatten one side of the cut surface. A third step of forming a magnetic pole and joining the polished surfaces of another cut composite block with low melting point glass to form a composite block structure in which the main magnetic pole is sandwiched, and recording on the composite block after the third step. The fourth step is to form the winding grooves of the reproducing windings in a cross-shaped pattern from the slider surface side, which is the sliding surface, across the main pole, and after forming the winding grooves, the composite block is shaped into the dimensions of the magnetic head core. After cutting, the slider that becomes the sliding surface is processed into a spherical surface.
A magnetic head for perpendicular magnetic recording formed by a fifth step of inserting a wound winding frame into the main magnetic pole and bonding the winding frame to the winding groove in contact with the sliding surface, and a method for manufacturing the same. The bonding surfaces between the soft magnetic block, the slider, and the cut composite block are fused using glass, improving reliability, and the recording/reproducing winding is in contact with the magnetic recording medium surface.
Since the magnetic head is wound on the main pole close to the sliding surface, the recording and reproducing characteristics are improved compared to conventional magnetic heads of this type.

Since it interlinks with the winding of the section, recording and reproducing efficiency is improved. Also, winding using a winding frame greatly facilitates the winding work.
