方法などが取り入れられている。2. Description of the Related Art Generally, in a magnetic disk device,
Contact start / stop (hereinafter referred to as CSS) is performed in which a magnetic head slider (hereinafter referred to as head slider) travels in contact with a magnetic disk medium (hereinafter referred to as medium) when the apparatus is started and stopped. Further, at the time of steady rotation, the head slider flies or contacts the medium at a certain interval, but the interval is narrowed as the performance of the apparatus is improved. Therefore, if the lubricant from the medium adheres to the head slider, a phenomenon of adsorption between the head slider and the medium occurs when the device is stopped, which causes a device failure. According to Japanese Unexamined Patent Publication No. 59-203240, the surface of the medium is covered with a deposition-promoting monolayer to prevent it. According to Japanese Examined Patent Publication No. 6-64869, provision is made by providing an organic silicon functional group layer chemically bonded to the surface of the head slider. Further, according to Japanese Patent Laid-Open No. 4-1984, a method is adopted in which the head slider surface is made porous and a lubricant is contained therein.

る。However, even with these methods, it is difficult to prevent adsorption of the lubricant from the medium or viscous foreign matter such as other grease due to adhesion to the head slider. . Further, with the increase in high-density recording in recent years, the flying distance between the medium and the head slider becomes narrower, so that the lubricant of the medium easily adheres to the head slider. Therefore, it is estimated that the lubricant adhered to the side surface of the head slider after long-term operation flows into a very small gap between the air bearing surface of the head slider and the medium after stopping. There is a problem in that the lubricant that has flowed in becomes a negative pressure due to the capillary phenomenon, and the head slider and the medium are attracted to each other.

とが容易に可能となる。In order to achieve the above object, according to the present invention, even when a medium lubricant or other viscous foreign matter adheres to the head slider surface, the adhered matter is evaporated. It is characterized in that adsorption can be prevented by storing it. Further, by using this means, it is possible to prevent the lubricant from adhering to the head slider from the medium without providing a complicated layer on the medium surface or the head slider surface or complicatedly processing the head slider surface. It becomes possible to do it easily.

超えていた。The results of actually evaluating the head slider 1 of the present invention will be shown. As a test of the head slider alone, first, three examples of the head slider 1 of the present invention and the conventional head slider were compared in a single plate tester. The results are shown in Fig. 3. In the test, the head slider was levitated above the same radial position on the medium for 300 hours.
The amount of lubricant of the medium used at this time was about 1.5 times as thick as the commercial base. As a result, about 10 5 μm 3 of lubricant adhered to the outflow end side surface 4 of the head slider 1. Immediately after the end of the flying test, in the head slider 1 of the present invention, as a result of applying an electric current to the heat generating part 5 for about 1 minute, all the lubricant adhering to the outflow end side face 4 disappeared and 10 2 μm 3 or less. (Fig. 3-1). Then, the head slider 1 of the present invention
Was left stationary on the medium for 48 hours. The results of measuring the adsorption force after standing were all 1.5 times or less than the initial value. On the other hand, the suction force similarly measured for the conventional head sliders was more than three times the initial value.

電流を流しても良い。As described above, as a result of passing the current through the heat generating portion 5, the adhered lubricant could be removed by evaporation. Moreover, it has been clarified that the current is not limited to be kept flowing at all times, but may be made to flow at an appropriate time and at an appropriate interval. From this, for example, after operation,
It can be seen that the adsorption phenomenon can be efficiently prevented by passing an electric current immediately after stopping by CSS. In addition, as a control method, a current may be applied during a free time during which magnetic recording / reproduction is not performed during operation.
