本発明は記録再生用の磁気ヘッド支持機構に関し、特に
電磁変換素子を支持する支持機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head support mechanism for recording and reproduction, and particularly to a support mechanism that supports an electromagnetic transducer element.

ある。In order to improve recording density in magnetic storage devices, a technical improvement goal is to make the track width for recording signals as small as possible. Conventionally, the track width for recording information in magnetic disk devices, VTRs, etc. that has been put into practical use is 2.
The track width is 0 to 30 μm, and it is an important technique to accurately position the magnetic head in such a narrow track width.

ない。The conventional magnetic head support mechanism described above has, for example, an opening/closing mechanism.
As shown in Japanese Patent Application Laid-Open No. 5-22296, Japanese Patent Application Laid-open No. 59-180855, and Japanese Patent Application Publication No. 61-17594, a gimbal spring and a load spring are formed into an integrated structure by welding or the like, and this structure is a rigid body. It is fixed to a certain head arm. Such a structure does not have sufficient rigidity in the transverse direction of the track, and is also larger in size than an electromagnetic transducer, so it easily induces vibrations, and is therefore not desirable from the standpoint of track positioning. I can not say.

Stop while holding. Therefore, there is a drawback that the air bearing surface and sliding surface of the electromagnetic transducer are attracted to the recording surface of the magnetic recording medium.

は磁気記録媒体の記録面に押圧されない。FIG. 1 is a partial perspective view showing an embodiment of the magnetic head support mechanism of the present invention. In FIG. 1, an electromagnetic transducer 2 for reading and writing data recorded on a magnetic recording medium is fixed to one end of a flat gimbal spring 1 made of stainless steel or the like, and the other end is It is fixed to the head arm 3 which is a rigid body. This head arm 3 has a rectangular shape with a crank-shaped bent portion 3a, and a load spring 4 having a pressing bent portion 4a for pressing the electromagnetic transducer 2 is attached to one surface of one end thereof. , and the other end of the gimbal spring 1 is similarly attached to the back surface. Next, on the opposite surface of the gimbal spring 1 from the side where the electromagnetic conversion element 2 is held, an embossment 1a in the shape of a semicircle with a height of about 0.2 mm is provided, and the other end of the load spring 4 This embossing 1a
The structure is such that a load is applied to the electromagnetic transducer 2 by contacting and pressing it. Further, a hole 3b is provided approximately at the center of the crank-shaped bent portion 3a of the head arm 3.
A load adjustment rod 5 passes through this hole 3b parallel to the head arm 3 and in the direction of the electromagnetic conversion element 2. Also,
One tip of the load adjustment rod 5 contacts the forward part of the pressing bending portion 4a of the load spring 4, and the other end is connected to a reciprocating drive mechanism (not shown) using, for example, an electromagnetic solenoid or a piezoelectric element. connected. The tip of the load adjusting rod 5 can reciprocate within a range from position A to position B by operating a reciprocating drive mechanism using a predetermined electric signal. When the tip of the load adjustment rod 5 is at position iA, the tip does not contact the load spring 4, that is, the tip of the load spring 4 is embossed 1a on the gimbal spring 1.
, the gimbal spring 1 is displaced and the electromagnetic transducer 2 is pressed against the recording surface of a magnetic recording medium (not shown). On the other hand, when the tip of the load adjustment rod 5 is at position B, the tip comes into contact with the load spring 4 and pushes up the pressing bending part 4a in the opposite direction. The gimbal spring 1 is not displaced away from the Enhos 1a, and therefore the electromagnetic transducer 2
is not pressed against the recording surface of the magnetic recording medium.

全く生じないという効果がある。As explained above, according to the magnetic head support mechanism of the present invention, the gimbal spring and the load spring are separately fixed to the head arm, so these structures are dimensionally smaller than the electromagnetic transducer. Therefore, unstable elements in positioning caused by vibration are eliminated. Furthermore, by simultaneously separating the gimbal spring and the load spring and using a load adjustment rod, it becomes possible to control the displacement of the load spring using electrical signals. Therefore, when the magnetic disk drive is not in use, it is possible to hold the electromagnetic transducer at a position away from the recording surface of the magnetic recording medium, so that the air bearing surface and sliding surface of the electromagnetic transducer can be aligned with the recording surface of the magnetic recording medium. The effect is that no adsorption occurs at all.
