[0009]

In recent years, with the spread of notebook personal computers and the performance of central processing units (CPUs), there has been a strong demand for thinner and larger-capacity magnetic disk drives. I have. Among them, regarding the increase in capacity, as shown in FIG. 27, in the magnetic disk device 8, the magnetic disk 8 serving as a storage medium is used.
Increase the number of a (3 magnetic disks in the case shown)
There is a way. In this case, the magnetic head device 1 must be provided on both surfaces of each magnetic disk 8a. Since the distance d between the magnetic disks 8a is determined by the total height H0 of the magnetic head device 1 as shown in FIG. 28, the stack height H1 of the magnetic disks 8a (FIG.
7), and the overall height of the magnetic disk drive 8 increases, which is against the demand for thinning.

The positioning of the head slider 2 with respect to the elastic support member 3 at the time of assembly is performed by abutment using a high-precision jig or alignment using an optical device, and heating is performed. It is necessary to hold the head slider 2 with respect to the elastic support member 3 until the adhesive 6 is cured by irradiation with ultraviolet light or ultraviolet light, which complicates the assembly work, takes time, and lowers the yield. There was a problem.

Further, a lead wire 5 to the magnetic head element 4
As shown in FIGS. 28 and 29, the lead wires 5 are formed with sufficient margin so that the lead wires 5 can be formed (loose) so as to follow the movements of the magnetic head element 4 and the head slider 2. Lead wire 5
Project from the side of the elastic support member 3. For this reason, depending on the case, the forming of the lead wire 5 may protrude toward the magnetic disk side, causing a problem that the magnetic disk may be damaged.

Further, as shown in FIG. 30, the magnetic head device 1 moves an air flow flowing in the traveling direction of the magnetic disk 8a between the head slider 2 of the magnetic disk 8a with respect to the rotationally driven magnetic disk 8a. Thus, the magnetic disk 8a flies with a very small flying height with respect to the surface thereof. Therefore, as shown in FIG. 31, the head slider 2 has a flat portion 2 facing the surface of the magnetic disk 8a.
a and the shape and size of the notch 2b and the depth of the notch 2b
The magnetic head element 4 is managed on the order of nm from the viewpoint of the reliability of running and stopping and the floating characteristics. Therefore, when the head slider 2 is fixed to the elastic support member 3 with the adhesive 6, if the adhesive 6 protrudes as shown in FIG. 32, the protruding adhesive 6 also acts as a plane portion of the head slider 2. As a result, there is a problem that the flying characteristics of the head slider 2 change.

In view of the above, the present invention provides a magnetic head device in which the whole is configured to be thin without changing the head slider and the positioning of the head slider is easily performed. It is an object.

Of 2b, cut-and-raised pieces 12b-3 and 12b-4 are:
The rigidity is set low by providing the round holes 31 on the respective folding curves. Thereby, the elasticity of the cut-and-raised pieces 12b-3 and 12b-4 is improved.

FIGS. 11 to 13 show a fourth embodiment of the magnetic head device according to the present invention. 11, the magnetic head device 40 is the same as the magnetic head device 10 of FIG.
1 has the same structure as that of the magnetic head device 10 shown in FIG. 1 except that a film conductive pattern 41 disposed along the longitudinal direction of the surface of the elastic support member 12 is provided instead of the lead wire 14 in FIG. It is.

This film conductive pattern 41 corresponds to FIG.
As shown in (2), for example, similarly to a flexible printed board, it is configured by forming a conductive pattern 41b on a base 41a made of a flexible film.
In the illustrated case, the conductivity of the conductive pattern 41b is enhanced by gold plating 41c on the surface. Further, one end of the film conductive pattern 41 extends to the vicinity of the magnetic head element 13 at the edge of the head slider 11 attached to the tip of the elastic support member 12, and the contact portion 41d is arranged as shown in FIG. As shown, the cut-and-raised piece 12b facing the magnetic head element 13

May be formed. In this case, the thin processing is performed by, for example, half etching. As a result, the flexibility of the cut-and-raised piece 12b in the region of the contact portion 41d is enhanced. As shown in FIG. 17, the elastic deformation of the thin portion 12c causes the connection terminal 13a of the magnetic head element 13 of the contact portion 41d. Is stabilized.

According to the magnetic head device 40 having such a configuration, when the head slider 11 to which the magnetic head element 13 is attached is mounted on the tip of the elastic support member 12, the head slider 11 is attached to the elastic support member 12. Notch hole 1
In 2a, it is fitted between the cut-and-raised pieces 12b. As a result, the head slider 11 is accurately positioned and temporarily fixed with respect to the elastic support member 12, and the contact portion 41d at one end of the film conductive pattern 41 is moved by the magnetic head based on the elasticity of the cut and raised piece 12b. By being pressed against the connection terminal 13a of the element 13, the element 13 is electrically connected. And the elastic support member 12
The adhesive 15 is filled between the cut-and-raised piece 12b and the head slider 11 and hardened, whereby the head slider 11 is fixedly held to the elastic support member 12. In this case, since the adhesive 15 has the notch hole 12a, even if it protrudes, the adhesive 15 does not swell up to near the upper surface of the head slider 11. Therefore, the protruding adhesive 15 does not affect the flying characteristics of the head slider 11.

Thus, the magnetic head device 40 is completed,
Thereafter, the other end of the film conductive pattern 41 is connected to a signal control device of the magnetic disk device in an assembly process of the magnetic disk device.

In this case, each connection terminal 1 of the magnetic head element 13 at the contact portion 41d at one end of the film conductive pattern 41
The electrical connection to 3a is made by fitting the elastic support member 12 of the head slider 11 provided with the magnetic head element 13 into the notch hole 12a.

Incidentally, the conventional film conductive pattern 4
In order to make an electrical connection in the magnetic head device using No. 1, the electrical connection between the film conductive pattern and the connection terminal of the magnetic head element is made by, for example, the following gold ball bonding or ultrasonic welding of the tongue terminal. Was sometimes performed. More specifically, first, as shown in FIG.
In a state in which the head slider 11 and the elastic support member 12 are fixed and held, as shown in FIG. 19, while heating from below the jig 42, the gold ball 44 supported on the tip of the capillary 43 is The contact part 41e exposed at one end and the connection terminal 13a of the magnetic head element 13
And pressure and ultrasonic vibration are applied. Thereby, as shown in FIG. 20, the contact portion 41e and the connection terminal 13a are electrically connected to each other. In this case, a heating unit, a pressing unit, an ultrasonic vibrating unit, and a capillary for sending out the gold ball are required, which causes a problem that the equipment cost increases and the material cost of the gold ball increases. .

Further, such a film conductive pattern 4
In some cases, the electrical connection is made as follows in the magnetic head device using No. 1. That is, for example, FIG.
As shown in FIG. 1 and FIG.
The so-called tongue terminal 41f is formed by extending the conductive pattern 41b at one end in a tongue shape. And gold plating 4 on both sides
1c, and as shown in FIG. 23, while the magnetic head element 13, the head slider 11, and the elastic support member 12 are fixedly held using the jig 45, the tongue terminal 41f is It is pressed against the connection terminal 13a of the magnetic head element 13. Thereby, each of the tongue terminals 41f is ultrasonically welded to the connection terminal 13a, and the tongue terminal 41f and the connection terminal 13a are electrically connected to each other. In this case, there is a problem that the bellows terminal 41f and the gold plating 41c on both surfaces thereof are required, and an ultrasonic vibration means is required, so that the equipment cost is increased.

On the other hand, the magnetic head device 40
In the above, the electrical connection of the contact portion 41d at one end of the film conductive pattern 41 to each connection terminal 13a of the magnetic head element 13 is performed within the notch hole 12a of the elastic support member 12 of the head slider 11 provided with the magnetic head element 13. Of the magnetic head element 13 corresponding to each contact portion 41d.
Is pressed by the corresponding connection terminal 13a.
Since no special equipment and materials are required and no special skills are required, the operation can be easily and reliably performed even by a non-skilled operator. Therefore, the number of steps in the assembling process can be reduced, the equipment cost and the assembling cost can be reduced, and the environmental reliability of the electrical joint can be improved.

In the above-described embodiment, the magnetic head device used in the magnetic disk device has been described. However, the present invention is not limited to this, and may be used for recording or reproducing other types of disks such as a magneto-optical disk and an optical disk. It is apparent that the present invention can be applied to a magnetic head device used in the disk device described above.

As described above, according to the embodiment of the present invention, the head slider 11 is attached to the elastic support member 12 while being inserted into the notch hole 12a of the elastic support member 12, so that the head slider 11 is magnetic. The entire head device 10 is configured to be thin. Therefore, even with a large-capacity magnetic disk device having a large number of magnetic disks, the entire magnetic disk device is configured to be thin. Further, since the head slider 11 is positioned and temporarily fixed by the cut-and-raised piece 12b on the periphery of the notch hole 12a provided at the tip of the elastic support member 12, positioning of the head slider 11 can be performed accurately and with a small number of work steps. Is easily done by Therefore, a jig for positioning is not required, and a jig for temporary fixing when the adhesive is cured is also unnecessary. Since the cut-and-raised piece 12b is in contact with the head slider 11, the conductive resin for ground connection also becomes unnecessary. It becomes unnecessary.

When the lead wire 14 is guided from the magnetic head 11 to the back surface of the elastic support member 12 through the notch hole 12a, and is led along the side edge of the elastic support member 12, The lead wire 14 is connected to the elastic support member 12
Since the lead wire 14 extends rearward through the notch hole 12a, the protrusion due to forming (looseness) of the lead wire 14 does not protrude to the magnetic disk side.
There is no contact with the surface of the magnetic disk.

When a film conductive pattern 41 is used instead of the lead wire 14, a contact portion 41d at one end of the film conductive pattern 41 is disposed on the surface of at least one cut-and-raised piece 12b of the elastic support member 12. As a result, the magnetic head element and the head slider 11
Is inserted into the notch hole 12a of the elastic support member 12, the contact portion 41d of the film conductive pattern 41 disposed on the surface of the cut-and-raised piece 12b is directly connected to the corresponding connection of the magnetic head element 13. Pressed by terminal 13a. As a result, the film conductive pattern 41 is connected to the magnetic head element 13 without providing a special wiring step.
