。Floating head sliders include those that generate only positive pressure and those that generate positive pressure and negative pressure. The force generated on the head on a rotating disk in the direction opposite to the medium is called positive pressure, and the force in the direction of the medium is called negative pressure. For the slider that generates only positive pressure as described above, the force to balance the positive pressure is
Since this external force must be applied from the outside and is constant, when the medium is not rotating, that is, when no positive pressure is being generated, the external force becomes excessive and has an adverse effect on the surface of the medium. For this reason, the slider is provided with a function of generating a negative pressure that causes the slider to approach the medium. This is the floating head slider that generates the above-mentioned positive pressure and negative pressure. Details are described in Japanese Patent Application Laid-Open No. 59-98347.

成されていた。As shown in FIG. 2, this type of conventional floating head slider has two rails l1 and 12 that extend approximately parallel to the running direction of the recording medium, and the longitudinal axis of the slider that is located between these rails and is approximately perpendicular to these rails. The cross rail 21 was arranged to connect the two rails 11 and 12.

して作用する。The two parallel rails 11 and 12 and the cross rail 21 form the same plane, and are used as a surface for generating positive pressure, that is, levitation force. The two parallel rails 11
The area surrounded on three sides by l2 and the cross rail 21 is a step surface 40 that is recessed by about 1 to 10 μm from the plane formed by these three rails 11, l2 and 21, and the area is a stepped surface 40 that is recessed by about 1 to 10 μm from the plane formed by these three rails 11, l2 and 21. Acts as a surface that generates a suction force.
従来の浮動ヘッドスライダは上述のように負圧が広い面
積を持つ段差面40で発生するため、媒体表面変動に対
する追従性が極めて乏しかった。In the conventional floating head slider, as described above, negative pressure is generated on the stepped surface 40 having a wide area, and therefore, the ability to follow medium surface fluctuations is extremely poor.
このためディスク表面に微小な突起がある場合や、ゴミ

欠点があった。Therefore, if there is a minute protrusion on the disk surface, or if dirt enters between the disk and the slider, it will easily collide with the protrusion, resulting in a head crash.
本発明の目的はこのような浮上系の追従性を改善した負
圧利用の浮動ヘッドスライダを提供することにある。An object of the present invention is to provide a floating head slider that utilizes negative pressure and has improved followability of the flying system.

ることにより構成される。The floating head slider of the present invention includes two rails on both sides arranged substantially parallel to the running direction of a recording medium, and a cross section between them, the longitudinal axis of which is arranged substantially perpendicular to the two rails. In a floating head slider including a rail, the upper cross rail is separated from the two rails on both sides and arranged approximately at the center of the floating head slider, and the air outlet end of the cross rail is located at the center of the cross rail in the width direction. only the portion parallel to the outflow end of the slider.

うにラッピングにより加工されている。The floating head slider of the present invention is composed of two rails 11 and 12 extending substantially parallel to the running direction of a magnetic recording medium (not shown), and a cross rail 21 located between these rails. Tapered portions 13 and 14 are formed on the front end sides of the two rails 11 and 12, and head elements 31 and 32 are formed on the rear end sides. Further, the surfaces of the rails 11 and 12, excluding the tapered portions 13 and 14, and the surface of the cross rail 21 are processed by lapping so as to form the same plane.

く領域は深さl〜IOμmの段差間40となっている。On the other hand, the area between the rails 11 and 12 excluding the cross rail 21 is a step gap 40 with a depth of 1 to IO μm.

出端16に平行な底辺25を形成している。Further, both sides of the cross rail 21 are separated from the two parallel rails 11 and 12. Furthermore, only the center portion of the air outlet end of the cross rail 21 in the width direction is a base 25 that is parallel to the air outlet end 16 of the slider.
Both sides of the base 25 are oblique sides 26 and 27. With the above configuration, rails 11 and l2 and cross rail 2
Positive pressure is generated on the surface of the magnetic recording medium 1 due to the air flow accompanying the running of the magnetic recording medium. In addition, an attractive force, that is, a negative pressure, is generated in the step surface 40 on the rear end side of the cross rail 21 in the direction of the magnetic recording medium. As described above, the floating head slider of the present invention has two parallel rails 1l and 12 with a cross rail 2l.
The air outlet end of the cross rail 21 is arranged only in the center, and only the center part of the air outlet end of the cross rail 21 forms a bottom side 25 parallel to the air outlet end 16 of the slider.
