In particular, in order to effectively adjust the posture of the head slider 3 in accordance with the vertical movement of the media 1, it is necessary to design the stiffness of the spring 6 to be approximately equivalent to the rigidity of the media 1. The situation is extremely inadequate from the perspective of improving vibration/impact performance.

7 is inserted. These attitude adjustment screws 17 are fastened to female threads provided on a substantially flat arm 20 that is disposed at a position facing the carriage 19 at a predetermined interval. Furthermore, the arm 20 and the posture adjustment plate 16

調整で微細かつ最適にコントロールできる。On the other hand, in order to improve vibration resistance/shock resistance, it is desirable to first make the carriage 19 and arm 20 systems as rigid as possible. Here, in particular, if the relative displacement between the carriage 19 and the arm 20 can be restrained by some means, ensuring good contact between the upper and lower heads 14 and 15 to the media 1 depends on part processing/assembly tolerances. This cannot be achieved without adjustment. The allowable tolerance for the head 14.15 to hit the media 1, which sufficiently guarantees the input/output characteristics, is that the head 14.15 can be considered to have almost no rigidity because the media 1 itself, which is made of resin with a thickness of several tens of microns, has almost no rigidity. determined by the relative positional relationship of In the case of a disk drive device using a floppy disk as a medium, it has been experimentally confirmed that relative angular deviation tolerance between heads is such that a tilt error of several tens of minutes is not allowed in each of the rolling and pitching directions. For example, if the head 14 on the carriage 19 side is considered as the reference, the arm 20
The mechanical assembly tolerance and the surface inclination of the joint surface of the head slider containing the head easily exceed the inclination tolerance of several tens of minutes. Therefore, in this embodiment, arm 2 on the adjustable side
The attitude adjusting plate 16 of Example 0 is changed in the rolling and pitching directions by independently raising and lowering the attitude adjusting screws 17, and the carriage 19 (the head 14 of II
The relative inclination between the movable head 15 and the head 15 on the movable side can be adjusted within tolerance. In particular, it is possible to make adjustments while monitoring the signal in playback mode using a medium on which the signal has already been recorded. Furthermore, the amount by which the heads 14 and 15 are pushed into each other through the media 1 can be finely and optimally controlled by adjusting the parallel movement of the attitude adjustment screw 17.

量産時のコストダウンにも大きく貢献するものである。In particular, by increasing the rigidity of the posture adjusting plate 16 and the pressing spring 18, vertical fluctuations caused by the rotation of the media 1 are corrected and eliminated between the opposing head sliders 13 and 14. Furthermore, by improving the apparent unit rigidity seen as a head system, the vibration/shock resistance performance can be improved by several to several tens of times compared to the conventional one. That is, compared to the conventional gimbal method, which only considers a rigidity approximately equivalent to the rigidity of the media, this method has the advantage of being able to freely set the rigidity of the attitude adjustment plate/pressing spring system. Furthermore, by adopting this method, the processing/assembly accuracy required for each part can be made rougher than in the past.
This also greatly contributes to cost reduction during mass production.
なお、押圧バネ18は例えば、姿勢調整ネジ17と同軸
一体化して用いても可能である。Note that the pressure spring 18 may be used coaxially with the attitude adjustment screw 17, for example.

締結の方向は上下どちらからでも一般性は失わない。In this embodiment, only one side (the arm side is taken as an example) is provided with an adjustment mechanism, but the carriage 19, arm 20
It goes without saying that it may be provided on both sides. Further, the generality can be maintained even if the direction of screw fastening is from above or below.

されている。Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 2 is a partial perspective view of the recording/reproducing apparatus in the embodiment. The difference from the first embodiment is that, at the tip of the arm 20, a part of the posture adjustment plate 16 is directly fixed to the arm body by adhesive or integrally, and on the other hand, the female threaded part 25 provided on the arm 20 is fixed directly to the arm body. The structure is such that one or more push-in adjustment screws 24 can be pushed in from above the arm. The point at which the tip of the push adjustment screw 24 acts is
It is set at an appropriate portion near the free end of the posture adjustment plate 16 fixed to the arm 20. A head slider 13 is fixed to the lower surface of the attitude adjustment plate 16, just as in the above embodiment.

ため、量産性に極めて富むものとなる。The feature of this embodiment is that the attitude adjustment of the head slider 13 is
Rolling adjustment is performed by applying bending deformation of the posture adjustment plate 16 with the push adjustment screw 24, and pitching adjustment is performed by applying torsional deformation, and at the same time, it is possible to adjust the amount of push. In particular, by intentionally tilting the initial setting angle θ of the attitude adjustment plate 16 in one direction as shown in FIG. 2, the ± angle can only be adjusted in one direction (in the example in FIG.
rolling adjustment). Furthermore, since the posture adjustment plate 16 substitutes for the action of the pressing spring 18 used in the first embodiment, the number of parts is reduced and the adjustment work can be simplified, making it extremely suitable for mass production.

に対して振動/衝撃モデル的に切り離すことができる。A third embodiment of the present invention will be described below with reference to FIG. FIG. 3 shows a partial plan view of the recording/reproducing apparatus in the embodiment. The difference from the first embodiment is that in addition to the pressure spring 18, a buffer body 21 made of damping material is provided in the space narrowed between the posture adjustment plate 16 and the arm 20. It is in. When frictional vibrations such as stick-slip or natural vibrations occur between the head sliders 12 and 13 sandwiching the media 1, these vibrations are absorbed by the attitude adjusting plate 16 to which the head slider 13 is fixed.
It propagates directly to the arm 20 via the pressure spring 18. From the perspective of vibration, the pressure spring 18 functions to improve the apparent rigidity of the head slider support system, and does not exert a damping effect once vibration occurs for some reason. By providing the buffer 21 as in this embodiment, one unit consisting of the head slider 13 and the attitude adjustment plate 16 can be moved to the arm 20.
can be separated using a vibration/impact model.

における耐振性の大幅向上が図れることが確認された。Therefore, by designing the arm 20 and the carriage 19 with a predetermined rigidity, improvement in performance against actual vibration/impact can be adjusted only by selecting the damping constant of the buffer 21. It has been confirmed that when this method is adopted, vibration resistance can be significantly improved, particularly near the natural frequency (300 to 400 Hz) of the media system, which is likely to occur in the current system.

The difference from the third embodiment is that a substantially cylindrical rotation block 22 rotatably fitted to the arm 20 is provided near the attachment portion of the head slider 13 on the arm 20. Below the rotation block 22, as in the third embodiment, there is a head slider 13. Posture adjustment plate 16. Posture adjustment screw 17
, a pressure spring 18 and a buffer body 21 are installed in a predetermined arrangement. Thus, although the rotating block 22 apparently functions as part of the upper arm 20, the upper and lower heads 14.
15 relative azimuth alignment (alignment of the deviation angle between the signal recorded on the medium and the helad gap) can be easily performed by adjusting the rotation of the rotation block 22. After adjustment, the rotation block 22 can be fixed by bonding means such as adhesive. Furthermore, from the viewpoint of output matching and maintenance of the upper and lower heads, the rotary block 22 can be handled as a type of head unit, which is an extremely practical means.
