摘要： The present invention is aimed at providing a magnetic disk and a magnetic disk apparatus both of which have a high performance lubricating film which makes continuous sliding endurance and low adhesiveness compatible, and a lubricating film having a self repairing function which makes it possible to recombine scratched off lubricating agent from the magnetic disk surface by sliding with a head onto the magnetic disk surface. The lubricating film comprises at least two kinds of lubricating agents each of which forms an individual layer, the layers being laminated. An adhesion enhancing layer is formed between a magnetic film and a lubricating agent at the surface of the magnetic disk, and the adhesion enhancing layer is fixed onto the magnetic film surface. Then, the adhesion enhancing layer and the lubricating agent are combined. The adhesion enhancing layer and the lubricating agent form a salt or complex body, and the lubricating agent can repeat adsorption and desorption with the adhesion enhancing layer reversely by a thermal reaction.

摘要： A magnetic storage apparatus includes a substantially non-flexible magnetic recording medium, a magnetic head slider having a reading/writing element mounted therein and liquid lubricant provided on the surface of the magnetic recording medium. The liquid lubricant is a liquid in a Newtonian range having a viscosity which is substantially constant irrespective of a shear rate or a liquid having the property that the actual viscosity is increased with increase of the shear rate. The magnetic head slider maintains a gap between the slider and the magnetic recording medium to perform reading and writing while being moved on the liquid lubricant intermittently or continuously in a contact manner with the liquid lubricant. There is provided a device for maintaining a constant flying height even if a movement speed is varied, which flying height is represented by the size of the gap. Thus, the magnetic storage apparatus of the liquid bearing system or the contact system has only very small forces such as liquid drag force and friction force or sticking force and is capable of performing stable slider movement, performing high-speed seeking operation with high reliability and performing high-density recording.
摘要翻译：磁性存储装置包括基本上非柔性的磁记录介质，具有安装在其中的读/写元件的磁头滑块和设置在磁记录介质表面上的液体润滑剂。液体润滑剂是牛顿范围内的液体，其粘度基本上恒定，与剪切速率无关，或液体具有实际粘度随着剪切速率的增加而增加的性质。磁头滑动器在滑动器和磁记录介质之间保持间隙，以便以与液体润滑剂接触的方式间歇地或连续地在液体润滑剂上移动来进行读写。提供了一种用于保持恒定飞行高度的装置，即使移动速度变化，飞行高度由间隙的大小表示。因此，液体轴承系统或接触系统的磁存储装置仅具有非常小的力，例如液体拖曳力和摩擦力或粘着力，并且能够执行稳定的滑块移动，以高可靠性执行高速寻找操作，执行高密度录音。

摘要： According to the invention, there is provided a carriage arm assembly including a carriage arm having two arm members. The arm member is constructed in such a way that the width of its coil side end and the width of its suspension side end are narrower than that of its intermediate area. This construction widens a servo band width, improves positioning accuracy, and reduces positioning errors of a magnetic disk apparatus, so that recording density is improved and storage capacity is increased. Further, by coupling two arm members using a restriction member via a visco-elastic member, it is possible to achieve a high damping effect on various vibration modes including in-plane bending of the arms, and suppress vibration of the carriage so as to reduce the positioning errors.

摘要： An acceleration detecting apparatus for a magnetic disk apparatus capable of detecting with high reliability the disturbances such as rotational and translational shocks and vibrations applied externally to the magnetic disk apparatus to thereby prevent destruction or the like damages of data recorded on a disk of the magnetic disk apparatus upon occurrence of off-track event under the influence of the disturbance. The apparatus includes a pair of acceleration detectors for detecting acceleration in two directions extending discretely in parallel to each other. The acceleration detectors are disposed at positions closer to the magnetic disk relative to a pivot shaft for a head supporting arm as viewed in a longitudinal direction of an oblong box-like casing of the magnetic disk apparatus in a plane which forms an angle not greater than 10 degrees relative to the plane of the magnetic disk. By employing the angular acceleration detectors in combination with an angular velocity detector, the rotational disturbances due to rotational shock/vibration can be detected with much enhanced reliability, and destruction of the data recorded on the magnetic disk due to the off-track read/write operation can positively be prevented.
