DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a support mechanism for a head slider used for recording and reproducing in a #4 FIm memory storage device.

[Technical background of the invention]

In a magnetic storage device using a magnetic tape+a disk or the like as a storage medium, recording to or reproduction from the storage medium is performed using a t-head slider.

The support mechanism of this Herad slider for recording and reproduction is used when seeking recording tracks on the surface of the storage medium.

The head slider is required to have high rigidity in the theta direction and sufficient strength against the frictional force generated between the helidene slider and the storage medium surface, as well as the adhesive fluid force. Rolling (rotational motion about an axis parallel to the running direction of the storage medium) and pitching (rotational movement perpendicular to the running direction of the storage medium and parallel to the storage medium surface) of the slider so that it can contact or follow at a minute interval. It is required to have a suitable degree of flexibility to be able to perform rotational movements about the axis.

In order to meet such demands, a head slider support mechanism as exemplified in FIG. 1 has conventionally been used.

In the same figure, the tip of the load beam lri is tapered, and a reinforcement flange 2 is provided on its inner edge.

In a head slider support mechanism with such a structure,
Attachment of head slider lO and attachment member 5.

When attaching the attachment member 5 and the load beam l, it is necessary to strictly define the positional relationship between each member. This means that the relative positional relationship between the carriage fixing part 4 and the helide slider 10, and the relative positional relationship between the load applying protrusion 8 and the helide slider 10 determine the performance of the support mechanism and, ultimately, the magnetic storage device into which it is incorporated. This is because it is an important point.

[Problems with background technology]

Generally, when mass producing a product, it is necessary to take into consideration the shape and I'11 degree of each component that makes up the product, as well as ensuring assembly accuracy when assembling each part and item.
Particularly for parts that require high precision, it is desirable to avoid assembly problems by integrating parts, and if integration is not possible, use a design that does not require much assembly precision.

From this point of view, when considering the conventional henode slider support mechanism shown in Fig. M1, the assembly of the head slider lO and the mounting member 5 and the assembly of the mounting member 5 and the load beam 10 both require an assembly precision of A degree #L. The problem is that this is not sufficient for mass production while maintaining product quality.

At the same time, a head slider attachment portion r is continuously extended between the tips of these cantilevers, and a head slider is attached to this head slider attachment portion.

[Example of actual invention]

Hereinafter, the seventh embodiment of the present invention will be described with reference to FIGS. 2 to 94.

The load beam used in the support mechanism of the present invention consists of a beam body 21, an elastic part n connected integrally to one end 11!l (on the left end side in the figure), and the other end of this elastic part. and a carriage fixing part integrally connected to the side.

In the movable head fixing part, the head slider is fixed to the movable arm 24 by a screw 25a and/or an m-joint part 25b, etc., for moving the head slider to any recording trunk 7. and the beam main body 21 to generate a force that presses the lid slider 2 onto the surface of the magnetic storage medium. A flang j is provided on the inner edge of the beam main body 21 in order to reduce the weight of the beam and increase mechanical rigidity.

The other end of the load beam 21 (the right end in the figure) is shown in Figure 3 (a
