本発明は磁気ディスク記憶装置の磁気ヘッドスライダに

浮動形スライダとして用いる°に好適な磁気ヘッドスラ
イダに関する。Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a magnetic head slider for a magnetic disk storage device, and particularly to a magnetic head slider suitable for use as a floating slider that holds a magnetic head on a disk with a minute gap. Regarding the head slider.

テーバフラット形スライダが用いられている。該スライ
ダは、左右２本のレール面を備え。As a conventional magnetic head slider for a magnetic disk storage device, for example, a Taber flat slider described in Japanese Patent Publication No. 56-52380 has been used. The slider has two rail surfaces on the left and right.

の磁気ヘッドスライダではレール面の最後流端と円板と
の隙間も同じに小さくしなければならない。The air bearing force acting on the rail surface causes the slider to float above the disk surface with a small gap between the slider and the disk surface. At this time, the most downstream end of the rail surface is closest to the disk surface. Furthermore, the magnetic head is provided so that the line connecting the rearmost ends of the two rails coincides with the magnetic gap. In order to increase the storage density of magnetic disk drives, it is necessary to minimize the gap between the disc and the head, but with conventional magnetic head sliders, the gap between the trailing edge of the rail surface and the disc is also the same. It has to be made smaller.
レール面が円板に近付くと小さな塵埃や小さな円板面の
凸起によってレール面が受ける浮上刃が減少しでレール
面と円板との接触する頻度が増大する欠点があった。When the rail surface approaches the disk, small dust particles and small protrusions on the disk surface reduce the amount of floating blades that the rail surface receives, resulting in an increased frequency of contact between the rail surface and the disk.
本発明の目的は、塵埃や円板面の凸起によって浮上量が
低下してスライダと円板面の接触頻度の増大をもたらす
ことがなく、かつ、磁気ヘッドの磁気ギャップ面と円板
面との間隙は微小化できる高密度磁気記録に適した磁気
ヘッドスライダを提供することにある。It is an object of the present invention to prevent the flying height from being reduced due to dust or convexities on the disk surface, resulting in an increase in the frequency of contact between the slider and the disk surface, and to prevent the magnetic gap surface of the magnetic head and the disk surface from increasing. The object of the present invention is to provide a magnetic head slider suitable for high-density magnetic recording in which the gap can be miniaturized.

させることができる。The distance between the rail surface and the disk surface of the slider is large on the upstream side and small on the downstream side. That is, the rail surface is inclined with respect to the disk surface. This is necessary in order to generate an air bearing effect. Therefore, in the present invention, a magnetic head is provided further downstream than the trailing end of the rail in a plane including the rail surface, and the magnetic head is brought close to the disk surface. As a result, the distance propagation between the rail surface and the disk surface remains the same as before, so the reduction in flying height due to dust or convexities on the disk surface is kept small as before, and only the magnetic head is placed on the disk surface. can be placed close to.

The tapered portion 2' and the rail surface 3' interact with each other to create an air bearing effect with the disk surface, giving the slider 1 a floating edge. 5 and 6 are members constituting the magnetic head 9, and one end of the member is connected to the downstream end of the slider 1.

trn, so the distance B between the magnetic gap 7 and the disc is
h is 0.287zm. Q with conventional slider
Since h=0, h3=h2=0.4 μm, so in this example, the ? The flying height is the same as the conventional type, and the flying height at the magnetic gap is 0.12 μ compared to the conventional type.
When the gap between the rail surface 3.3' and the disk surface becomes smaller than before, the rail surface 3 becomes smaller due to small dust and convexities on the disk surface, which were not a problem in the past.
, 3' may be reduced and the clearance may be reduced during operation, increasing the chances of contact between the slider 1 and the disc 4. In order to avoid this, it is necessary to remove even smaller particles than before and to finish the disk surface even more smoothly, but this increases cost. According to this embodiment, the rail surface 3.3' and the disc 4
The gap between the surfaces of the disk 4 is the same as that of the conventional type, increasing the chance of contact between the disc 4 and the slider 1.Moreover, since the magnetic gap 71 is closer to the surface of the disk 4, the storage density is higher than that of the conventional type. It has the advantage that it can be made into a nog density. Moreover, it does not cause an increase in varnish.
