る効果がある．[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a magnetic head support device and a magnetic disk drive device, and particularly relates to a thin head support structure and one suitable for a magnetic disk device that is intended to be miniaturized. ．． [Prior Art] In a conventional magnetic disk device, for example, as described in U.S. Pat.
The structure has a magnetic head mounted on the surface of the gimbal that faces the magnetic disk. [Problem to be solved by the invention] In order to increase the capacity of magnetic disk drives, it is essential to increase the number of recording media, but to do so, it is necessary to reduce the height of the head and its support. It has become important to do so. As the number of media increases, the space between the media other than the head insertion section becomes completely unnecessary. In the conventional technology described above, the gimbal section is provided on the magnetic converter core of the magnetic head, so it is not possible to lower the gimbal mounting height of the head while keeping the core height constant. ．． In other words, even if an attempt was made to lower the height of the head slider other than the magnetic transducer, the gimbal section was large and would collide with the magnetic transducer, making it impossible to lower the height. An object of the present invention is to obtain a fermentation-type magnetic head support device that maintains or improves the performance of the magnetic head and high-speed access, and also to obtain a small-sized, large-capacity magnetic disk device. [Means for solving the problem] The above object is to make the cross-sectional shape of the head mounting part that supports the head a structure with both edges bent, and to make the magnetic transducer part less than the height of both edges bent. for,
This is achieved by arranging the bent portions of both edges to overlap along the direction of extension of the head attachment portion. [Function] Between a plurality of stacked magnetic disks, head mounting portions for supporting the head facing one side of one disk and the other side of the other disk are arranged in pairs, or are arranged in pairs. When installed, both edges of the folded structure overlap, making it possible to keep the height of the pair of head mounting parts low, and to narrow the disc spacing. (Embodiment) A first embodiment of the present invention will be described below with reference to Figs. 1 to 5. Fig. 5 is a plan view of a swing-type magnetic disk device including a magnetic head support device of the present invention. On the base 1 are a spindle part 3 that rotates a magnetic disk 2, which is a magnetic recording medium in which a plurality of sheets are stacked, and an actuator part 4 that moves the head to an arbitrary position on the disk 2.
is installed. The actuator section 4 is composed of a bearing section 5 for rotational support, a voice coil motor 7, a head arm section 8, and a load arm 9 which is a head mounting section provided at the tip thereof. A slider 10 constituting a magnetic head is disposed on the tip side of the load arm 9 via a gimbal section to be described later. A floating rail is provided on the surface of the slider 10 facing the disk 2. The floating rails of the head arm section 8, load arm 9, and slider 10 are arranged so that their extending directions are parallel to the extending line passing through the center of the rotation axis of the seven actuators described above. In such a structure, the airflow accompanying the rotation of the disk 2 flows along the extension direction of the slider 10, the load arm 9, and the head arm section 8.
No compressive force is generated in load arm 9. Figure 1 shows
A side view of this load arm 9 is shown, FIG. 2 is a plan view of the slider 10 and gimbal section 12 at the tip of the load arm 9, and FIG. 3 is an enlarged view of the slider 10 portion in FIG. , Figure 4 shows the cross-sectional shape of the load arm 9. In FIGS. 1, 2, and 3, the magnetic transducer 11 includes a core 17 and a coil 18, and is provided at the rear of the slider 10. The magnetic transducer 11 is configured to levitate by 0.1 to 0.3 μm above the rotating disk 2 based on the principle of hydrodynamic bearing.
The slider 10 described above is supported via a gimbal 12 which is flexible and positioned at the tip side of a load arm 9 which has the function of pressing its center portion against the medium side. That is, a thin gimbal 12 is bonded to the back surface of the slider 10, and the other end of this gimbal 12 is connected to the load arm 9 via a spacer 14. Further, there is a hemispherical pivot 13 near the center of the slider of the gimbal 12, and the load arm 9 is configured to press the apex of this pivot with a force of about 8 to 15 gf. In such a load arm 9, the one located below and the one located above the stacked disks 2 are fixed with a fixing plate 15 in between, and this fixing plate 15 is further fixed on the head arm 8. It is fixed with screw 16. The cross section of the upper and lower load arms 9.9 is a bent plate structure with both edges 9A and 9B as shown in Fig. ) is an acute angle, and the other side (edge 9A side in this example) is an obtuse angle. In this example, they are 80@ and 100°. Therefore, the upper and lower load arms 9, 9 are configured so that the respective bending positions of the two arms 9A, 9B are the same, and the bending edges overlap. In addition, as an input/output line from the magnetic converter 11, a flexible printed line (FPC) 2
0 is pasted on the load arm 9. This FPC2
0 is a copper printed wire 21 coated with polyimide resin 22. Next, the shape and dimensions of this example will be explained. As shown in FIG. 3, the core height hc of the slider 10 from the floating surface 10a is higher than the height hp from the floating surface 10a of the slider 10 to the pivot mounting portion. That is, h c >
h p. Furthermore, as shown in Fig. 4, when heads are arranged on both sides of the multilayer disk 2, the distance ho between the upper and lower load arms 9, which are placed back to back, is less than twice the load arm height h1. can do. That is, whereas in the conventional case h o > 2 h A, in this embodiment, ha < 2 ha. Therefore, as shown in FIG. 1, the distance ha between the disks 2 is .000, ignoring the floating height. hm=2hp+ho. When such a head is inserted into the mounting portion of the disk 2 and assembled, it is necessary to perform the work without damaging the head. 6th
The figure shows this assembly jig. The assembly jig is disk 2
It consists of a support base 25 and a support support 26, which are aligned in height, and a simulated media plate 27 fixed to the support support 26. When the support 26 is moved toward the disk from the state shown in Figure 6. The head is inserted between the disks in a state where the convex end 2a and the concave dummy medium plate end 27a are in contact and the height is determined. According to this first embodiment, it is possible to realize a thin head support structure with an extremely low height. Furthermore, the slider 10 is thin and lightweight, making high-speed seeking possible. Also, since the height of the load dome and the slider center of gravity become closer during seek, the rolling performance during seek becomes more stable. Next, the first
, and a second embodiment in which the slider and core portion are different.
The third and fourth embodiments will be explained with reference to FIGS. 7, 8, and 9. In the example shown in Figure 7, core a
1 is made up of a separate member from the slider 10, and is a composite head built into one of the floating rails of the slider 10. The height of this composite core 31 is higher than the height of the slider 10. The effects of this example are as follows:
It is extremely suitable for mass production because it is possible to realize a thin head and there is no need to add a step to the slider during manufacturing. In the example shown in FIG. 8, a thin film head portion 32 is fabricated on the rear surface of a slider 10 with a step. According to this embodiment, it is possible to realize a yeast-shaped head section suitable for high recording density. The example shown in FIG. 9 is shown in FIGS. 1 to 3. The protrusion 10a and fob are left at the inlet end corner of the first embodiment 710. The height of these protrusions 10a, 10b is equal to the core height at the outflow end. According to this embodiment, since the height of the opposite surface is the same in order to obtain the flatness of the slider air bearing surface and it is easy to fix during processing, it is possible to realize a thin head with high precision. Next, the first embodiment and the fifth and sixth embodiments, which have different gimbal parts, will be explained with reference to FIGS. 10 and 11. In the example shown in FIG.
4 has a slider 10 fixed to its tip end, and the other end fixed to the load arm 9 with three spot welds 37. According to this embodiment, it is possible to realize a thin head with strong rigidity in the direction of the direction of the sea.
In the example shown in FIG. 11, the slider 10 is fixed to the tip side of the gimbal part 35, and the slider 10 is fixed to the other end side or the tip of the load arm 9 with a rigid base arm 36 at three spot welds 37. There is. The spacer arm 36 is arranged so that its tip side leaves a slight gap with the side surface of the slider 10 and maintains a non-contact state. In a magnetic disk drive, when a head sticks to a disk, there is a risk that the gimbal 35, which is an elastic body, will be significantly deformed. Therefore, by applying a force to the head in the direction of sheathing (upward in FIG.
The tip of the slider 6 directly contacts the slider 10 and applies a tangential force,
Stickiness can be avoided. As described above, this embodiment has the effect of realizing a highly reliable thin head that can cope with head adhesion. Figures 12 and 13 show other examples of the head support device. The load arms 9, 9 forming the upper and lower pair are the first
It is shown in Figure 3. As shown in the cross-sectional shape, the bending angle of the edges 9A and 9B of the load arm 9.9 is 90', and the edge height ha is higher than the height ha of the pair of load arms, and as shown in FIG. This is because the heads that touch the top and bottom surfaces of the disk 2 are shifted in the direction of the central axis. That is, by shifting the two load arms 9, 9 back to back in the axial direction, the cross-sectional width changes, and even if the edges of the load arms are bent at right angles, they will not interfere with each other. Therefore, according to this embodiment, it is possible to realize a thin head with a high rigidity of the load arm. Figure 14 shows another embodiment of the assembly jig. This example is the 6th
In the example shown in the figure, the end 2a of the disk 2 and the simulated medium 27
The shape of the end portion 27a is different. The cut direction of the end 2a of the disk 2 is changed so that a contact force is applied in the opposite direction to that of the adjacent disk end 2b. According to this embodiment, it is possible to realize a thin head assembly jig that allows easy machining of the disk end face. [Effects of the Invention] According to the present invention, an extremely thin magnetic disk head can be realized, which has the effect of increasing the capacity of a magnetic disk device.
