本発明は回転形アクチュエータを有する磁気ディスク装
置の浮動形磁気ヘッドに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a floating magnetic head of a magnetic disk drive having a rotary actuator.
回転形アクチュエータを有する磁気ディスク装置におい
ては、第1図に示すように磁気ディスク1上のスライダ
2はアクチュエータ3の回転に伴い、空気流の周速方向
とスライダ2の長手方向とのなす角、すなわちヨー角θ
が変化する。このヨー角θは磁気ディスク1の回転方向
に対しておよそ±15°程度である。In a magnetic disk drive 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 circumferential velocity direction of the air flow and the longitudinal direction of the slider 2. That is, the yaw angle θ
changes. This yaw angle θ is approximately ±15° with respect to the rotational direction of the magnetic disk 1.
この種の磁気ディスク装置に用いられるスライダ2は、
第2図および第3図に示すようにその長手方向にテーパ
部4aとフラット部4bとからなるスライダレール4を
備え、このスライダレール4のサイドエツジ部5を加工
上の理由および損傷防止の観点から、例えば45°程度
の大きな面取りを施していた。このため、ヨー角θが大
きくなった場合、前述した面取部により、スライダ2の
浮上量が急激に減少し、磁気ディスク1とスライダ2と
が接触しやすくなり、最悪の場合にはスライダ2が墜落
し、磁気ディスク1の記憶面を破壊することがあった。The slider 2 used in this type of magnetic disk device is
As shown in FIGS. 2 and 3, the slider rail 4 is provided with a tapered portion 4a and a flat portion 4b in the longitudinal direction, and the side edge portion 5 of the slider rail 4 is For example, a large chamfer of about 45° was applied. For this reason, when the yaw angle θ increases, the flying height of the slider 2 rapidly decreases due to the chamfered portion described above, making it easier for the magnetic disk 1 and the slider 2 to come into contact with each other, and in the worst case, the slider 2 crashed and destroyed 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ので、ヨ
ー角が増大しても、浮上量の減少を抑えることができる
浮動形磁気ヘッドを提供することを目的とする。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 reduction in flying height even when the yaw angle increases.
本発明の特徴は、スライダのスライダレールにおける片
側または両側のサイドエツジ部に、軸受作用部を形成し
、ヨー角が増大したときのスライダに流入する空気の横
方向流れに対して軸受作用を発揮させるようにしたもの
である。A feature of the present invention is that a bearing action portion is formed on one or both side edge portions of the slider rail of the slider, and a bearing action is exerted against the lateral flow of air flowing into the slider when the yaw angle increases. This is how it was done.
以下本発明の実施例を図面を参照して説明する。 Embodiments of the present invention will be described below with reference to the drawings.
第4図および第5図は、本発明の磁気ヘッドを構成する
スライダを示すもので、図において第2図および第3図
と同符号のものは同一部分である。FIGS. 4 and 5 show a slider constituting the magnetic head of the present invention, and in the figures, the same reference numerals as in FIGS. 2 and 3 indicate the same parts.
スライダ2のスライダレール4のサイドエツジ部には、
軸受作用部として例えばその長手方向に沿って微小深さ
のステップ部6が設けられている。At the side edge of the slider rail 4 of the slider 2,
For example, a step portion 6 having a minute depth is provided along the longitudinal direction as a bearing action portion.
このステップ部6は、スライダ2のヨー角θが増大した
とき生じるスライダ2の側面方向から流入する空気流に
対して圧力上昇の助走区間としての働きをなす。このス
テップ部6の深さDは5μm以下が良好である。This step portion 6 functions as a run-up section for increasing the pressure of the airflow flowing in from the side surface of the slider 2 that occurs when the yaw angle θ of the slider 2 increases. The depth D of this step portion 6 is preferably 5 μm or less.
次に上述した本発明の磁気ヘッドの動作を説明する。Next, the operation of the above-described magnetic head of the present invention will be explained.
スライダ2が第1図に示すように、磁気ディスク1の中
間に位置するときには、スライダレール4には空気が平
行に流入するため、正常な浮上刃を得ることができる。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 floating blade can be obtained.
しかし、スライダ2の磁気ディスク1の開始また終了時
に相当する位置にあるとき、すなわちヨー角θが大きい
ときには、スライダ2の側面から空気が流入することに
なり、従来のものでは浮上安定性が良好でないが、本発

用を果たす。このため、ヨー角なしの場合と同程度の圧
力を発生し、スライダ2の浮上量低下を防止することが
できる。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 angle θ is large, air flows in from the side of the slider 2, and the conventional slider has good flying stability. However, in the present invention, the step portion 6 functions as a run-up section for increasing the pressure of air flowing in from the side surface of the slider 2. Therefore, it is possible to generate the same pressure as in the case without a yaw angle, and to prevent a reduction in the flying height of the slider 2.
なお、上述の実施例はステップ部6を、スライダレール
4の両側のサイドエツジ部に設けたが、片側のサイドエ
ツジ部にのみ設けても同様の効果を得ることができる。In the above-described embodiment, the step portions 6 are provided on both side edge portions of the slider rail 4, but the same effect can be obtained even if the step portions 6 are provided on only one side edge portion.
また、以上説明した実施例においては、軸受作用を果た

限るものではない。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.

きる。As described in detail above, the present invention does not reduce the flying height of the slider even when the yaw angle of the slider becomes large, and can improve the flying stability of the slider, thereby preventing the slider from falling and preventing the storage surface of the magnetic disk from falling. can prevent the destruction of
