いる。However, as the magnetic disk medium surface becomes smoother to increase the recording density of magnetic disks, the problem of the magnetic hent slider becoming more likely to stick to the magnetic disk medium surface while the magnetic disk is stopped has arisen. Therefore, there is a need for a method that can prevent such failures as easily as possible.

・ムンロード機構を挿入配置することは困難である。(C) Prior Art and Problems In order to simply solve the problem of adhesion of the magnetic hent slider to the magnetic disk medium surface mentioned above, it would be a shame to adopt a load/unload mechanism instead of the C3S method. Recently, with the miniaturization of magnetic disk devices, the spacing between each magnetic disk has been narrowed to just a few cranes, so it is difficult to insert and arrange a loading/unloading mechanism for a magnetic head between these magnetic disks. It is.

該媒体に接触するように配設されている。FIG. 1 is a schematic diagram for explaining an embodiment of a magnetic disk loading method according to the present invention, in which a magnetic disk medium 1 mounted in a magnetic disk device has a thickness shape at the center of the medium 1. It has a shape that becomes thinner toward the peripheral end (radial direction), that is, it has a tapered shape. Further, the magnetic slider 2 for the magnetic disk medium 1 has a second
A zero-load negative pressure slider having the load characteristics shown in the figure is used, and at a predetermined seek start position A of the magnetic disk medium 1, a predetermined support height h of O: 2 to 0.3 fins is used.
When a seek operation is performed in the direction of the center of the magnetic disk medium 1 while the magnetic disk is supported at a distance, and reaches the moving seek position B,
It is arranged so as to be in contact with the medium.

を有している。The stable flying height of the negative pressure type magnetic head slider 2 is obtained from the relationship between load, positive pressure, and negative pressure. As is clear from the pressure curve C, etc., there is a region where d (load)/dh > d (positive pressure - negative pressure)/dh, so it has a hysteretic floating characteristic.

おいて所定支持高さｈａで保持されることになる。Therefore, the method of the present invention is as follows: FIG. 1 and FIG. 21! In other words, the negative pressure magnetic slider 2 is placed at the predetermined seek start position A6 of the magnetic disk medium 1 when the magnetic disk medium 1 is started and stopped. The slider 2 at 'this position'A remains stationary at the predetermined support height ha even when the magnetic disk medium '1 is driven to rotate. And in loading, the front
After starting and rotating the magnetic disk medium 1, when the slider 2 is moved to the seek position B by performing a seek operation toward the center of the magnetic disk medium 1, the slider 2
floats to a minute height of he for the first time. After that, if the slider 2 is operated in the direction of the predetermined seek start position □λ□, the slider 2 continues to float at the specified flying height. Even if the object seeks to the seek start position A, the flying height does not change due to the hysteresis phenomenon and the object continues to fly stably. On the other hand, when the magnetic disk medium 1 is stopped, the floating slider 2 is moved to a predetermined seek start position A, and then the rotating magnetic disk medium 1 is stopped. When the magnetic disk medium 1 stops, the slider 2 is unloaded and held at the seek start position A at a predetermined support height ha.

Incidentally, even when using a hard gimbal with a noni spring stiffness of 2 to 3 g/vsva to support the negative pressure magnetic head slider 2, the gap between the negative pressure magnetic head slider 2 and the magnetic disk medium 1, which has a flying height of O. The influence of positional fluctuations on flying height fluctuations is at most about 1% and is not a problem.
