本発明は磁気ディスク装置に使用する磁気ヘッドアセン
ブリに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head assembly used in a magnetic disk drive.

アセンブリは磁気ヘッドを搭載して磁気記録媒体上を摺

持機構は磁気記録媒体表面に平行な方向、すなわち媒体
の円周方向と半径方向に高い剛性を有する必要がある。A magnetic head assembly that reads and writes signals on a rotating magnetic recording medium has a magnetic head mounted on it, a head slider that slides or floats above the magnetic recording medium, and a head slider that holds the head slider and presses it against the magnetic recording medium with an appropriate load. Consists of a support mechanism. This head slider support mechanism needs to have high rigidity in the direction parallel to the surface of the magnetic recording medium, that is, in the circumferential direction and radial direction of the medium.

ヘッドスライダ１０と反対の方向に折り曲げたフランジ
部３２とすることにより剛性を高めていた。For this reason, in the conventional magnetic head assembly, as shown in FIG. 3, both side edges of the load beam 31 of the head assembly are formed into flange portions 32 bent in the direction opposite to the head slider 10, thereby increasing the rigidity.

剛性が損なわれ、有害な機械振動を発生するという欠点
があった。Magnetic disk drives are becoming smaller and more dense, and along with this, the spacing between disk plates is also becoming narrower. As the spacing between the disk plates becomes narrower, the magnetic head assembly that fits therein must also be made thinner. However, in the conventional magnetic head assembly described above, its thickness is the sum of the thickness of the head slider 10 and the thickness of the flange portion 32 of the quad beam 31, so there is a limit to how thin it can be made. . If this conventional magnetic head assembly is intended to be thin, there is no other way than to reduce the thickness of the flange portion 32 of the p-dobe beam 31. However, if the flange portion 32 is made thinner, the above-mentioned rigidity in the direction parallel to the medium surface is lost, resulting in the generation of harmful mechanical vibrations.
従って本発明の目的は、記録媒体表面に平行な方向の剛
性を損なわずに薄型化できる磁気ヘッドアセンブリを提
供することにある。Therefore, an object of the present invention is to provide a magnetic head assembly that can be made thinner without impairing the rigidity in the direction parallel to the surface of the recording medium.

In a magnetic head assembly including a load beam having one end attached to a rigid arm and the other end holding a head slider, a flange is bent at a side edge of the load beam toward a surface of the head slider facing the recording medium. It is characterized by forming a part.

。Referring to FIG. 1, the magnetic head assembly includes a head slider 10 and a slider support mechanism 30. The slider support mechanism 30 is composed of a hood beam 31, a flexure 35, and a base 36, and the load beam 31 is approximately an isosceles triangle. The base 36 is attached by welding to the end corresponding to the bottom of the base 36.

Further, both side edge portions corresponding to two equal sides of the load beam 310 are flange portions 32 that are bent at a substantially right angle toward the medium facing surface 11 of the head slider 1O. The lead wire 21 connected to the head slider 10 passes through a tube 28 held by a claw 34 on one of the flange portions 32 of the load beam 31 and is guided toward the base 36 .

することができる。FIG. 2 shows a state in which the magnetic head assembly shown in FIG. 1 is mounted in a disk device. In FIG. 2, two magnetic head assemblies 9 are mounted back to back between two disk plates 57. It has been 7 years. In the magnetic head assembly 9, the flange portion 32 of the load beam 31 is bent toward the head slider 10 side, that is, toward the disk plate 57 side. Therefore, the flange portion 32 and the head slider 10 can partially overlap in the thickness direction. Therefore, it is possible to reduce the thickness of the magnetic field assembly without reducing the thickness of the flange portion 32. Therefore, it is possible to provide a magnetic head assembly that can be made thinner without impairing the rigidity in the direction parallel to the disk plate.

This has the effect of being thinner without impairing the rigidity in the direction parallel to the disk plate.
