にした装置構成に関するものである。[Detailed description of the invention] (Summary)
The present invention relates to a magnetic disk device, and more particularly, to a magnetic disk device in which the lubricity of a lubricating film on the surface of a magnetic disk to a magnetic head slider and the floating state of a magnetic head slider can be maintained stably at all times. This relates to the device configuration.
近来、磁気ディスク装置においては高密度記録化に伴っ

ドスライダの浮上間隙を益々狭くすることが要求されて
いる。In recent years, in magnetic disk drives, as the recording density has increased, there has been a demand for increasing the number of magnetic films in the magnetic disk to four layers and for narrowing the flying gap of the magnetic head slider.

着が生じ易く、磁気へッドスライダの浮上状態を不安定
にしたり、またヘッドクラッシュが生じる傾向がある。As the flying height of the magnetic head slider becomes lower, the probability that the flying magnetic head slider contacts and collides with the surface of the magnetic disk increases, making wear and damage more likely to occur. Covered with a lubricating film, etc. However, depending on the state of the lubricant film, head adhesion tends to occur, making the floating state of the magnetic head slider unstable, and head crashing tends to occur.
このため、磁気ディスク表面に被覆された潤滑膜の磁気
ヘソドスライダに対する潤滑性を常に一定にして、磁気
ヘッドスライダの低浮上状態を安定に維持し得る装置構
戒が必要とされている。Therefore, there is a need for an apparatus configuration that can maintain the magnetic head slider in a stable low flying state by keeping the lubricity of the lubricating film coated on the surface of the magnetic disk constant for the magnetic head slider.
磁気ディスク装置では高密度記録化に伴って磁気ディス
クに対する磁気ヘッドスライダの浮上間隙も益々狭めら
れ、接触、衝突する確率が増加して磁気ディスク表面及
び磁気ヘソドスライダが摩耗、或いは損傷し易くなる。In magnetic disk drives, as recording density increases, the flying gap of the magnetic head slider relative to the magnetic disk becomes increasingly narrower, increasing the probability of contact and collision, making the surface of the magnetic disk and the magnetic head slider more susceptible to wear or damage.
従って、そのような障害を防止し、磁気ディスクの耐久
性を向上するため、該磁気ディスクの表面には潤滑剤を
塗布するか、または潤滑膜を被覆することが提案されて
いる。Therefore, in order to prevent such failures and improve the durability of the magnetic disk, it has been proposed to apply a lubricant or coat the surface of the magnetic disk with a lubricant film.
また、ディスク・ヘッド間への塵埃の混入に起因するヘ

れて外気と遮断された構成が用いられている。Further, in order to prevent head crashes caused by dust entering between the disk and the head, these mechanisms are sealed and isolated from the outside air.

性を低下させる問題がある。However, the lubricating film applied to the surface of the magnetic disk to prevent the above-mentioned failures and improve the durability of the magnetic disk actually causes head adsorption and disturbs the flying state of the magnetic head slider relative to the magnetic disk. There is a problem in that the durability is reduced.

姿勢が不安定になって乱れ、該磁気ディスク表面に衝突
して損傷させる欠点があった。In particular, when the magnetic disk is stopped, the magnetic head slider is in contact with the magnetic disk, and as the rotational speed of the magnetic disk increases, the magnetic head slider is slightly levitated to perform an access operation.
In a magnetic disk drive using the Stop) operation method, the magnetic head slider that is in contact with the magnetic disk when stopped is attracted by the adhesive-like action of the cohesive force of the lubricant film applied to the surface of the magnetic disk. Also, since such lubricant adheres and accumulates on the slider surface during contact sliding, the sliding state or the attitude of the flying magnetic head slider becomes unstable and disturbed, and may collide with the surface of the magnetic disk. It had the disadvantage of causing damage.

ある。In view of the above-mentioned conventional problems, the present invention has been developed so that a lubricating film with stable lubricity for the magnetic head slider is always formed on the surface of the magnetic disk, thereby stabilizing the floating state of the magnetic head slider and increasing the durability of the magnetic disk. The object of the present invention is to provide a new magnetic disk device with improved performance.

するように構戒する。In order to achieve the above-mentioned object, the present invention provides a device structure in which a magnetic disk, which is attached to a rotational drive mechanism and whose surface is coated with a lubricating film, a magnetic head slider, and a head access mechanism are sealed in an airtight container. In addition to providing an injection means for injecting liquid lubricant toward the disk surface, the liquid lubricant to be supplied to the injection means is supplied to the lower part of the airtight container, and the lubricant after being injected onto the disk surface is collected and reused. A circulation mechanism for supplying the fuel to the injection means is also provided.

スライダは恰も水で濡らしたガラス板面にガラス片を滑
らせた場合のように、液状潤滑剤を押し分けて滑走する
状態となる。In the present invention, a liquid lubricant is injected onto the surface of a rotating magnetic disk by a lubricant injection means immediately before the rotation is driven, so that the surface is constantly wetted with lubricant, and an unloaded magnetic head slider is pressed against the surface of the magnetic disk. By setting the magnetic head slider to a loaded state with a predetermined interval between them, the magnetic head slider is in a state where it slides by pushing the liquid lubricant apart, just like when a piece of glass is slid on a glass plate surface wet with water.

相対運動で流出しようとする潤滑剤の凝集力に起因する
吸引力によって定められる。In this state, the distance between the magnetic disk and the magnetic head slider is determined by the pressing pressure of the magnetic head slider, the resistance force when the lubricant between the disk and the slider is swept away by the pressing force of the slider, and the rear end of the magnetic head slider. It is determined by the suction force due to the cohesive force of the lubricant, which tends to flow out due to relative motion.

前記潤滑剤の噴射も停止させる。Therefore, even if the fluid liquid lubricant film on the magnetic disk surface becomes locally thick or thin, the magnetic hesode slider will not come into direct contact with the magnetic disk surface, and the above-mentioned Due to the suction force of the fluid lubricant film, a constant distance is maintained without jumping and a stable running condition is maintained. Then, when the rotation of the magnetic disk is stopped and the magnetic head slider is unloaded, the injection of the lubricant is also stopped.

Even if dust or the like gets mixed into the device, it is washed away by the liquid lubricant 3 that is continuously sprayed, and the dust is removed by the lubricant circulation mechanism through the collection hole 2l with the filter 20 provided in the base part 16. Since only the liquid lubricant 31 is efficiently filtered and circulated, damage to the magnetic disk caused by dust and the like is also eliminated.
