In a magnetic disk device having a rotary actuator, as shown in FIG. 1, as the actuator 3 rotates, the slider 2 on the magnetic disk 1 changes the angle between the peripheral speed direction of the air flow and the longitudinal direction of the slider 2. That is, the yaw angles θ 1 and θ 2 change. The yaw angles θ 1 and θ 2 are approximately +15° and −15° with respect to the rotational direction of the magnetic disk 1.

１の記憶面を破壊することがあつた。 As shown in FIGS. 2 and 3, the slider 2 used in this type of magnetic disk device includes a slider rail 4 consisting of a tapered portion 4a and a flat portion 4b in the longitudinal direction. For processing reasons and to prevent damage, the portion 5 is chamfered by a large angle of, for example, about 45°. Therefore, the coe angles θ 1 and θ 2 are 2°~
There is no particular problem when the angle is as small as 3 degrees, but when the yaw angles θ 1 and θ 2 become large, the flying height of the slider 2 rapidly decreases due to the chamfered portion described above, and the magnetic disk 1 and slider 2 In the worst case, the slider 2 could fall and destroy the storage surface of the magnetic disk 1.
本発明は、上述の事柄にもとづいてなされたも

を目的とする。
The present invention has been made based on the above-mentioned problems, and an object of the present invention is to provide a floating magnetic head that can suppress a decrease in flying height even when the yaw angle increases.

A feature of the present invention is that among the side edge portions on both sides of the slider rail of the slider, at least the side edge portion on the side in the air inflow direction due to the yaw angle,
A bearing action section is formed to exert a bearing action on the lateral flow of air flowing into the slider when the yaw angle increases.

Components with the same reference numerals as those in the figures and FIG. 3 are the same parts. At the side edge portion of the slider rail 4 of the slider 2, a step portion 6 having a very small depth is provided as a bearing acting portion, for example, along the longitudinal direction thereof. This step portion 6 is configured to adjust the yaw angle θ of the slider 2.
This acts as a run-up section for increasing the pressure of the airflow flowing in from the side surface of the slider 2, which occurs when the pressure increases. The depth D of this step portion 6 is
A value of 5 μm or less is good.
次に上述した本発明の磁気ヘツドの動作を説明

２の浮上量低下を防止することができる。 As shown in FIG. 1, when the slider 2 is located in the middle of the magnetic disk 1, air flows in parallel to the slider rail 4, so that a normal flying force can be obtained. However, when the slider 2 is at a position corresponding to the start or end of the magnetic disk 1, that is, when the yaw angles θ 1 and θ 2 are large, air flows in from the side of the slider 2, and the conventional slider cannot float. Although the stability is not good, in the present invention, the step portion 6 is similar to the slider 2.
Acts as a run-up section to increase the pressure of air flowing in from the side. Therefore, a pressure comparable to that without a yaw angle can be generated, and a reduction in the flying height of the slider 2 can be prevented.

ものに限るものではない。 In addition, in the above-mentioned embodiment, step portions 6 are provided at the side edge portions on both sides of the slider rails 4, 4 of the slider 2 as a countermeasure when the yaw angles θ 1 and θ 2 are large.
However, if one of the yaw angles θ 1 and θ 2 is small and the other is large, the step portion 6 is provided only on the side edge portion on the side where the yaw angle is large, that is, on the side in the air inflow direction due to the yaw angle. A similar effect can be obtained even if . Furthermore, in the embodiments described above, the step portion formed at the side edge portion of the slider rail 4 was explained as a bearing action portion that performs a bearing action. It is not limited to things.
