ドクラッシュ等を生じ致命的な障害となる場合がある。FCI Conventional technology and problems Conventionally, there are methods for loading a magnetic slider onto a magnetic disk by mechanically displacing it, such as the one-way method and the ramp loading method, but recently, constant start methods have been used.・Stop (C3
S) method is used. Although the C8S system is mechanically simple, it has many problems, such as the need for wet 118I treatment on the magnetic disk surface and the fact that the magnetic slider sticks to the disk surface when the device is stopped. The gap between the magnetic hent slider and the magnetic disk during operation of the magnetic disk device is determined by the buoyancy force (air bearing) of the airflow generated as the magnetic disk rotates, and the external force that pushes the magnetic hent slider against the surface of the magnetic disk. are maintained at a constant level, and information is recorded and reproduced on the magnetic disk in this state. Therefore, when the magnetic hent slider receives an abnormal excitation force, this gap changes, and this not only causes a change in signal amplitude, but also, in severe cases, causes the magnetic disk and magnetic head to come into contact, causing immediate This may cause a head crash, resulting in a fatal failure.

転を起動できなくなるなど問題が多い。As a countermeasure to this problem, the gap fluctuation can be reduced by increasing the rigidity of the air hair ring, but this generally requires increasing the force with which the magnetic slider is pressed against the surface of the magnetic disk. However, in the above-mentioned loading method, if there is any disturbance in the operating posture of the magnetic head slider when loading the magnetic head slider, the corners of the magnetic head slider may come into contact and damage the magnetic disk. The cSs method has many problems, such as significantly deteriorating the durability of the magnetic disk, and in extreme cases, the magnetic head may stick to the magnetic disk, making it impossible to start the rotation of the magnetic disk.

題を完全に解決することは困ゲ１ｔである。As a solution to the above problems, a so-called negative pressure slider has been proposed, which uses negative pressure to reduce the force pressing the magnetic hent slider against the disk surface.
As long as the 3S method is adopted, it is difficult to completely solve the problem of suction even with this slider.

FIG. 2 is a perspective view of a negative pressure slider (hereinafter abbreviated as a negative pressure slider). The structure of the negative pressure slider is characterized by the addition of a cross rail 4 to the structure of the conventionally used positive pressure slider, and this slider is placed on the magnetic disk at the site "rails 2 and 3" in the same way as before. When loaded, an air bearing is formed between the magnetic disk and this slider, creating a buoyancy force (19) J<, but in the concave portion 5, on the contrary, an attractive negative pressure acts between the two. In order to maintain the desired gap, it is necessary to apply a deterrent force from the outside that balances the buoyancy force, and this pressurization method applies a bouncing force to the slider support system. However, the present negative pressure slider 1 has the advantage of being able to maintain the gap even without such external force because the negative pressure slider 1 has the above-mentioned levitation force and suction force.

に困難である。FIG. 2 shows the relationship between buoyancy force and suction force during operation of the negative pressure slider. In FIG. 2(a), 1 is a negative pressure type slider, and 6 is a magnetic disk. The rotation of the magnetic disk 6 generates a levitation force Fp, but due to the above-mentioned attraction force Fa of the four parts 5, these two forces act on each other, and a balance is maintained in the gap ho, and the negative pressure slider 1 is forced to the magnetic disk 6. It operates stably. Figure 2 (bl shows the distribution of the levitation force Fp and attraction force Fa in the length direction of the negative pressure slider 1, respectively. Figure 3 shows the distribution of the levitation force Fp, attraction force Fa, and the magnetic force of the negative pressure slider 1. It shows the relationship with the gap between the discs.As can be seen from Figure 3, the suction force Fa is I, +!
The In force F has a much longer range than P, and this means that the negative pressure slider, which is initially placed at a distance from the magnetic disk, gradually approaches the magnetic disk due to the attractive force when the magnetic disk starts rotating. This shows that so-called self-loading is possible. When a modern negative pressure type slider is placed close to the surface of the magnetic disk at a distance of less than Ho using a support system with a spring force ro and the magnetic disk is rotated, (as the disk begins to rotate, The suction force applied to the slider increases, and as it approaches steady rotation, the suction force overcomes the spring force fo, and as a result, the slider becomes completely self-loading.Actually, more than 1 g In order to generate force, this Ho needs to be a gap of about 100 μm or less, but in practice, depending on the assembly and processing tolerances of the slider, the negative pressure slider can be self-conducted without touching the magnetic desk.

A mechanism is proposed in which the self-loading distance is set at a distance of 100 mm, and the self-loading distance is reduced to within Ho.

The support spring 7 is fixed to the arm 8, but in the present invention, a piezoelectric element 9 is disposed between the support spring 7 and the arm 8. This piezoelectric element 9 may be, for example, a laminated piezoelectric ceramic. Further, when the magnetic disk 6 is at rest, the negative pressure slider 1 is installed at a safe distance from the magnetic disk surface with a gap of 0.1 to 0.5 without fear of contact. When the magnetic disk 6 starts and reaches steady rotation, a pulse-like or vibrational electric excitation is applied to the piezoelectric element 9 to cause a corresponding displacement in the piezoelectric element, and the negative pressure slider 1 is moved to the distance of the cell ZI code. It is configured to move within Fill Llo. The displacement of the piezoelectric element 9 itself is from several μm to several tens of μm at most, but at the head portion of the negative pressure slider 1 attached to the tip α111) of the support spring 7, the displacement is from 0.1 to 0.
It can be expanded and displaced to 5 dragons, which is a practical and effective displacement. Furthermore, if the piezoelectric element 9 is driven in accordance with the resonance frequency of the support spring 7, the support spring 7 can be driven with a small amount of electric power.
A larger displacement can be obtained. Once the negative pressure slider 1 has moved within the distance Fi1['llo of the self-float, it is attracted toward the surface of the magnetic disk against the spring force fo, as shown in Fig. 4 (a+), and is balanced with the levitation force. This is shown in Figure 4 ([)].Therefore, strictly speaking, the suction force (
I'a) - floating force (fo) - buoyancy force (1'p)? j. Suction force F a is several tens of grams
, if the spring force ro is shifted from 1 to 28, Fa>fO,
Practical: No problems at all. In the above state, it is no longer necessary to drive the piezoelectric element 9. Piezoelectric element 9
The driving time is only a few ms to several tens of ms, and this time is short enough to bring the negative pressure slider 1, which is located at a distance of 0.1 to 0.5 degrees from the magnetic disk surface, within the self-loading gap 11o. It's time. When the rotation of the magnetic disk stops, the attractive force disappears, and the negative pressure slider 1 separates from the surface of the magnetic disk due to the spring force fo.

できる。In addition, as an application example, the piezoelectric element itself is a passive element, and when it receives an external force, it displaces and generates a voltage, so this principle can be used to detect abnormalities such as the crash of a negative pressure slider that occurs during the footsteps of a magnetic disk. It can be performed. That is, when such an abnormality occurs, displacement is applied to the piezoelectric element through the support spring system, which causes a voltage to be generated in the piezoelectric element, and by detecting this voltage, it is possible to detect a crash abnormality. Therefore, when the magnetic disk starts up, the piezoelectric element applies an excitation voltage to give displacement to the negative pressure slider, and during normal operation, it is connected to a detection circuit for field lightning detection, thereby detecting abnormalities in the belly button F system. Can be used.
